# Dark (TV series)

Dark is a German science fiction thriller television series co-created by the couple Baran bo Odar and Jantje Friese. It ran for three seasons from 2017 to 2020. The story follows dysfunctional characters from the fictional town of Winden in Germany, as they pursue the truth in the aftermath of a child's disappearance. They follow connections between four estranged families to unravel a sinister time travel conspiracy that spans several generations. The series explores the existential implications of time and its effect on human nature and life. It features an ensemble cast led by Louis Hofmann.
Dark debuted on 1 December 2017 on Netflix; it is the service's first German-language original series. The second season was released on 21 June 2019, while the third and final season was released on 27 June 2020.
Dark has received critical acclaim for its acting, direction, writing, tone, visuals, themes, musical score, and the ambition and complexity of its narrative. Many praised the show for its complex narrative structure, which required viewers to pay close attention to detail in order to understand the intricate connections between characters and timelines. The show's slow-burn pacing, atmospheric visuals, and philosophical themes were also lauded for elevating it beyond typical genre fare. The series direction, handled by Baran bo Odar, was praised for its careful attention to detail, mood, and tone, creating an eerie, tension-filled atmosphere that contributed to the show's success.
Dark was recognized for its ambitious storytelling and has been nominated for and won several awards. In 2021, the BBC ranked the series as the 58th greatest TV series of the 21st century.

## Overview

Children start vanishing from the German town of Winden, bringing to light the fractured relationships, double lives, and dark pasts of four families living there and unfurling a mystery that spans four generations.
The first season begins in 2019, but later grows to include 1986 and 1953 via time travel, when members of the show's central families become aware of a wormhole in the cave system beneath the local nuclear power plant. During the first season, secrets are revealed concerning the Kahnwald, Nielsen, Doppler, and Tiedemann families, and their lives begin crumbling as their ties are exposed. The conspiracy involves the missing children and the history of the town and its citizens.
The second season continues the families' attempts to reunite with their missing loved ones several months after the first-season finale, in 2020, 1987 and 1954, respectively. Additional storylines are set in 2053 and 1921. The second season introduces Sic Mundus Creatus Est, a major faction in the ongoing battle for the ultimate fate of the people of Winden and the world. The season counts down to the apocalypse.
The third season follows the four families across time in the wake of the apocalypse in 2020. It introduces a parallel world tethered to the first. The third season continues the 1954, 1987, 2020, and 2053 storylines in the first world, while also adding a new 1888 storyline and two 2019 and 2052 storylines in the second world, as the factions further their own desires for each world. The season also showcases the main events across all of these years, continuing the events of the season while also serving as backstory for the events of the first two seasons.

## Cast and characters

The first season takes place primarily in 2019 but expands to include stories set in 1986, 1953, and – in the final scene of the first season – 2052, with several characters portrayed at various ages by multiple actors.
The second season takes place several months after the first, depicting the initial stories in 2020, 1987, and 1954, respectively, while continuing the future-set storyline into 2053, and adding a fifth storyline, set in 1921.
The third season introduces a storyline based in 1888 and a parallel reality featuring alternate versions of many main characters.

| In June 2019, 43-year-old Michael Kahnwald kills himself. His mother Ines hides his suicide letter before anyone else notices it. On 4 November, after nearly two months of treatment at a psychiatric facility, Michael's teenage son Jonas returns to school and reunites with his best friend Bartosz Tiedemann, who has recently started dating Martha Nielsen, whom Jonas has a crush on. Erik Obendorf, the local town drug dealer, has been missing for two weeks, and police officer Ulrich Nielsen – the father of Martha and her brothers, teenager Magnus and pre-teen Mikkel – has been assigned the investigation, which struggles to uncover any clues. Meanwhile, Ulrich is cheating on his wife Katharina, the principal of the school, with Jonas's mother Hannah. While searching for Erik's stash of drugs in a cave not far from the town's soon-to-be-closed-down nuclear power plant, Jonas, Bartosz, the three Nielsen children, and Magnus' girlfriend Franziska are frightened by strange sounds and their flickering flashlights, and Mikkel disappears as they flee the cave. The next day, the body of a young boy is discovered, but it is not Mikkel. At an unknown location, a hooded figure straps Erik to a chair while clamping a mechanism around his head. ||||||

| Mikkel's disappearance brings back memories from 1986 when Ulrich's younger brother Mads vanished, and Ulrich starts believing that the disappearances of Erik, Mikkel, and the body of the third boy are related. While searching the caves, he finds a locked door leading to the nearby nuclear power plant, and although Ulrich's request to enter the power plant is refused by its director Aleksander Tiedemann, Bartosz's father, he is able to clear Erik Obendorf's father, a power plant driver, from his list of suspects. Police chief Charlotte Doppler is informed that the dead boy, dressed in a 1980s outfit, died only 16 hours earlier, and that his ears were destroyed by extreme pressure. Later, as lights start flickering and birds fall dead from the sky, Charlotte grows even more concerned. Meanwhile, an unkempt stranger checks into the hotel owned by Bartosz's mother Regina. Ulrich's mother Jana lies to Ulrich, claiming that her husband Tronte was with her the night of Mads's disappearance, while knowing he had left their house. At dawn, a disoriented Mikkel wakes up in the cave and runs home, only to discover via a newspaper on the doorstep that the date is 5 November 1986. ||||||

At the nuclear plant, newly elected director Claudia Tiedemann, Egon's daughter and Regina's mother, clashes with her predecessor Bernd Doppler, who informs her of secret barrels hidden in the nearby caves.

Meanwhile, as the town's electricity is flickering, a teenage Charlotte starts investigating the deaths of multiple birds, shy young Hannah has unrequited feelings for Ulrich, and Regina is being bullied and engages in self-harm. A flock of sheep is found dead from cardiac arrest with their eardrums ruptured, Mikkel escapes from the hospital and returns to the caves; after breaking his leg, he calls for help.

| In 2019, Jonas finds maps and notes about the caves in his family's garage, while Charlotte tries to find a connection between the disappeared boys and the dead birds, which – just like the dead boy – are found to have burst eardrums. The birds also show similar symptoms to birds found after the Chernobyl disaster, and Charlotte suspects connections to the Winden events of 1986. Meanwhile, her marriage to her husband Peter is crumbling since he was discovered to be having an affair with a transgender sex worker named Bernadette, and she finds evidence that Peter was out driving the night of Mikkel's disappearance, despite him claiming otherwise. Their oldest daughter, Franziska, confides in Magnus Nielsen that she plans to leave Winden due to her parents' wrecked marriage. Franziska's deaf younger sister, Elisabeth, is feared missing after not returning from school, but eventually comes home hours later, explaining that she met a mysterious man - Noah - who gave her a watch once apparently belonging to Charlotte. Meanwhile, Peter's father Helge, who is suffering from dementia, is found roaming the forest, claiming that he "must stop Noah". The next morning, a hooded figure approaches Elisabeth's friend, Yasin, and tells him that Noah has sent him. ||||||

In 2019, Yasin has also now vanished, and panic is starting to spread. Charlotte accuses Peter of being involved in the boys' disappearances. Hannah wants to resume her affair with Ulrich, but he angrily refuses. At the hotel, the Stranger tells Regina to deliver a package to Jonas while he is away for a few days. At Michael's grave, the Stranger approaches Jonas, telling him that Jonas' father once saved his life. Bartosz meets Erik Obendorf's drug supplier, who turns out to be Noah. Later, Jonas receives the Stranger's package, containing a light, a Geiger counter, and Michael's suicide note. In the letter Jonas' father explains that on 4 November 2019, he travelled back to 1986. There he stayed and grew up, raised by Ines, eventually marrying Hannah and fathering Jonas.

While she admits to resenting him for bullying her during their childhood, she makes him see that Hannah was the one framing him for rape. Visiting the morgue, Ulrich finally realises that the dead boy is Mads, not aged since 33 years ago. Meanwhile, Jonas fails to tell his mother about the suicide letter but enters the caves armed with his father's notes and the equipment from the package sent by the Stranger. Within the caves, he finds a door with a Latin phrase, Sic mundus creatus est ("Thus the world was created"), and he goes through. In 1986, after going through to the other side, Jonas notices flyers put up for the missing Mads Nielsen.

| In 1986, Helge, who was working at the plant the night Mads disappeared, is questioned by Egon about his whereabouts. The Stranger explains to Jonas that Mikkel is indeed his father and warns him that taking Mikkel back home to 2019 will result in Jonas never being born. Katharina unsuccessfully attempts to convince Egon that Ulrich never raped her, and Helge and Noah prepare to move Yasin's dead body from a bunker behind Helge's cabin. In 2019, the police are finally allowed to enter the power plant, and in the caves Charlotte finds a door that is welded shut. Ulrich finds Egon's 1986 notes, making Helge a suspect, and visits him at the nursing home. Frightened, Helge claims to be able to change the past and future. Ulrich is suspended from work and Katharina confronts him about his affair. Charlotte discovers that the cave system goes beneath an old cabin owned by Helge. She receives a voice message from Ulrich, stating that Helge is the kidnapper, but that the question is not how he is doing it, but when. Late at night, Helge leaves the nursing home, followed by Ulrich, who brings a book from Helge's room: Eine Reise durch die Zeit by H. G. Tannhaus. ||||||
| 8 | 8 | "What you sow, you will reap" "Was man sät, das wird man ernten" | Baran bo Odar | Martin Behnke & Jantje Friese | 1 December 2017 (2017-12-1) |
| In 1953, birds begin to die, and the unidentified bodies of Erik and Yasin are discovered. Police chief Daniel Kahnwald (Ines' father) and officer Egon Tiedemann are puzzled by the boys' odd outfits. Ulrich arrives from 2019 and meets several locals, including newcomer Agnes Nielsen and her son Tronte, who are about to rent a room in the Tiedemann house, and a watchmaker named H. G. Tannhaus, who disclaims knowledge of the book found in Helge's 2019 home. Through the young Ines and Jana, Ulrich learns of the two bodies, and when introduced to the 9-year-old Helge, he believes killing him will save the lives of the boys. He bludgeons Helge and leaves him for dead in the bunker. Later, Tannhaus finds Ulrich's smartphone. In 1986, the Stranger meets with an elderly Tannhaus, who shares his theory of time travel through wormholes. The Stranger confirms his theories and states that such a wormhole, allowing people to travel into the past or future though only in 33 year increments, exists in Winden. He asks Tannhaus to fix a broken brass device of his, so he can destroy the wormhole. Tannhaus later brings out the original version of the device, studying them side by side. ||||||
| 9 | 9 | "Everything Is Now" "Alles ist Jetzt" | Baran bo Odar | Jantje Friese & Marc O. Seng | 1 December 2017 (2017-12-1) |
| In 1986, teenage Ulrich is released without charges, and Hannah secretly discovers that a newly arrived young man, who calls himself Aleksander Köhler, is living under a false identity. When Bernd admits that the hidden barrels contain byproducts of a small meltdown, Claudia secretly hires Aleksander to weld shut the door to them. In an argument with Helge (revealing that the abducted boys died from Noah's attempt to create a time machine) Noah states his mission to free humanity, likening himself to the Biblical Noah. In 2019, Hannah blackmails Aleksander into destroying Ulrich's life. She lies to Katharina that Ulrich wanted to leave his family. Regina discovers the Stranger's research, and Jonas breaks up with Martha. Bartosz is approached by an elderly Claudia, his supposedly dead grandmother. Later, Bartosz meets with Noah and agrees to join him. In 1953, Helge has been reported missing, and Noah – appearing the same age as in 1986 and 2019 – offers pastoral support to Helge's mother, Greta. Ulrich is arrested and confesses to bludgeoning Helge with the intent of killing him. The Claudia of 2019 enters Tannhaus' shop with blueprints for the brass machine, asking him to build it for her. ||||||

In 1986, the elderly Helge is killed while attempting to stop his younger self by deliberately crashing his car into him. Jonas has also returned to 1986 to bring Mikkel back to 2019, but Noah and Helge kidnap him. Jonas wakes in the bunker, accompanied by the Stranger, who reveals himself to be the adult Jonas. The Stranger leaves to destroy the wormhole using the brass machine, which Tannhaus has completed from the broken version brought by the adult Jonas and Ulrich's smartphone. Claudia starts to read Tannhaus' book. In 2019, Charlotte uncovers a 1953 article on Helge's kidnapping, including a photo of Ulrich. Noah tells Bartosz that Claudia is their main adversary, and that the adult Jonas, unwittingly, is about to create the wormhole. In 1953, the child Helge regains consciousness as the wormhole appears, connecting him to Jonas in 1986.

In 2052 in Eva's world, Eva explains to the young Martha who just killed Jonas that Martha's death in Adam's world is the point at which two parallel realities overlap in quantum entanglement: in one scenario, alternate Martha saves Jonas from the apocalypse; in the other, Jonas survives on his own, eventually becoming Adam.

Claudia directs Adam to prevent the origin in a third, original world where H. G. Tannhaus created a time machine to prevent the death of his family, inadvertently destroying his world and splitting it into the worlds of Adam and Eva. Using quantum entanglement, Adam returns to the Apocalypse and takes young Jonas to Eva's world, urging him to collect Martha and prevent the origin. Adam then confronts Eva and, to her shock, refuses to kill her as she remembers discovering. Recognizing that the cycle has been broken, Eva embraces Adam. Jonas and Martha travel to the origin world through the passage in the cave and successfully save Tannhaus' family, thereby erasing both worlds from existence. The only main characters who remain in the origin world are those whose birth was not a result of time travel. Peter is in a relationship with Bernadette; Katharina and the cancer-free Regina are single; and Hannah is expecting a child with Bernadette's brother Torben Wöller, whose eye has healed. At a dinner party, Hannah notices a yellow raincoat in the corner of the room and experiences a brief moment of déjà vu. Asked what she will name her child, Hannah answers that she has always liked the name "Jonas". ||||||

| 2 | 100% (30 reviews) | 82 (4 reviews) |
| 3 | 97% (35 reviews) | 92 (4 reviews) |
Dark received critical acclaim and has been listed by many publications as one of the best TV shows of the years 2017, 2019, and 2020, as well as of the 2010s, 21st century, and of all time. Vulture included the series in its article A Guide to TV Shows in the 2010s as one of the most notable shows of the decade. The BBC ranked it the 58th best TV series of the 21st century. Meanwhile, BuzzFeed listed it as one of the 25 best TV shows of all time.

#### Season 1

The first season of Dark received mostly positive reviews from critics, with many noting its similarities to the TV series Twin Peaks and another Netflix series Stranger Things. The review aggregator website Rotten Tomatoes gave the first season an approval rating of 90%, with an average rating of 7.4 out of 10, based on 48 critics. The website's critical consensus is "Dark's central mystery unfolds slowly, both tense and terrifying, culminating in a creepy, cinematic triumph of sci-fi noir." Metacritic, which assigns a weighted average score out of 100 to reviews and ratings from mainstream publications, gave it a score of 61, based on ten reviews.
Writing for The Guardian, Lanre Bakare gave Dark a rating of four out of five and praised the series for its tone, the complexity of its narrative, and its pacing. Grading the series with a "B", Steve Greene of IndieWire wrote, "Even when Dark is clinical in its set-up of these interweaving story threads, there's still an incredible amount of energy coursing through the show." From Vox, Emily St. James gave it a score of three and a half out of five and said, "Dark is fun to try to solve — it's a treat to tease out the many connections running among the three eras. It's just that at a certain point, it becomes difficult to care about what's happening, beyond simply wanting to figure out how everything is connected." Ariana Romero of Refinery29 noted that the series was darker and more in-depth than Stranger Things. However, there was some criticism by Reason's Glenn Garvin for a heavy-handed approach to its message, a lack of sympathetic characters, and unoriginality of certain aspects of the series.
Los Angeles Times listed Dark as one of the best TV series of 2017, while Thrillist named it the 18th best TV show of the year.

#### Season 2

The second season received critical acclaim. On Metacritic, it received a score of 82 out of 100, based on four reviews. At Rotten Tomatoes, season two of the series holds an approval rating of 100% based on 30 reviews, with an average rating of 8.1 out of 10. The website's critical consensus states, "Dark's sumptuous second season descends deeper into the show's meticulously-crafted mythos and cements the series as one of streaming's strongest and strangest science fiction stories."
Critics referred to season two as ominous and much more bizarre than season one, and that the series managed to subvert several tropes regarding the concepts of time travel. The season received a rating of four out of five from Jack Seale of The Guardian and Boyd Hilton of Empire, a B+ grade from Hanh Nguyen of IndieWire, and an "amazing" score of 9 out of 10 from David Griffin of IGN. The latter wrote in his verdict: "Dark Season 2 can hurt your brain at times, trying to piece all the time-traveling narratives together, but in the end, creators Baran bo Odar and Jantje Friese reward your patience with some stellar WTF moments. At eight episodes in length, [it] is a tightly-woven tapestry of compelling stories and memorable performances from the entire ensemble." TV Guide's Kaitlin Thomas was also favorably inclined towards the season, saying that "one of the reasons Dark is such a compelling drama isn't just because it presents time travel as something that is possible or because it grounds its story in the emotional narratives of its characters, but because it couches its sci-fi themes in conversations about free will and destiny. [...] [It] excels at building a compelling mystery, and the fact that it never loses the plot itself is a testament to the writing of the series."
The season was included in many critics' year-end lists of 2019. It was ranked as the ninth and tenth best TV show of the year by Maggie Fremont of ScreenCrush and John Sellers of Thrillist, respectively. Outside the top ten, TV Guide and Complex named it the 12th and 26th best TV show of the year in their respective list. In addition, CNET and Vogue also listed it on each unranked list.

#### Season 3

The third and final season received critical acclaim, with the series finale receiving particular praise for being a satisfying conclusion to the story. It received a Rotten Tomatoes approval rating of 97% based on 35 reviews, with an average rating of 8.5 out of 10. The site's critical consensus says, "Dark's final chapter is as thrilling as it is bewildering, bringing viewers full circle without sacrificing any of the show's narrative complexities." At Metacritic, the season received an average score of 92, based on four reviews.
The season received a rating of five out of five from Radio Times's Patrick Cremona and four out of five from The Guardian's Jack Seale, an A− grade from IndieWire's Steve Greene, and an "amazing" nine out of ten from IGN's David Griffin. Cremona deemed it as "science fiction at its most mesmerising, its most confounding and its most exhilarating - and it all makes for a truly irresistible piece of television" and further praised the writing, cinematography, casting, and acting (particularly that of Louis Hoffman, Maja Schöne, and Lisa Vicari). Griffin wrote in his verdict, "Dark's third and final season on Netflix is a memorable journey through time and space, with thrilling character shifts and fascinating paradoxes to unpack." William Goodman of Complex praised the ending, saying, "Odar and Friese masterfully close by showing the symbiotic relationship between endings and beginnings. There's no victory without sacrifice, no light without darkness, and no love without loss. The tension between each of these conflicting ideas is so interwoven, making it hard to discern where one ends and the other begins. And so Dark concludes not with a hard endpoint on a line, but by elegantly and satisfyingly circling back into itself."
The season was listed by many publications as one of the best TV shows of 2020. Radio Times named it the eighth best TV show of the year, with one of the website's writers Patrick Cremona saying, "The final series was another irresistible piece of sci-fi television, equal parts mesmerising and confounding, with a sweeping scope that gave it the sense of a true epic. With its exhilarating finale, Dark has earned its place among the list of the very best original series made for the streamer." Exclaim! ranked it the tenth best TV series of the year. The website's Allie Gregory wrote, "With stunning performances from Louis Hoffman, Oliver Masucci and Karoline Eichhorn (and an incredible score to boot), the apocalyptic time travel sci-fi series deftly concludes its mind-bending journey in its darkest (and Dark-est) instalment yet. [...] [It] manages to neatly tie up all of its loose ends to finally find the one true "origin," so, at last, the town of Winden can free itself from the trappings of time and fate." GameSpot listed it as one of the year's ten best TV shows, with one of its writers Mike Rougeau stating, "what really impressed us about Season 3 is how it wrapped things up, even while continuing the tradition of adding yet another new dimension (so to speak) to the show's tangled timelines. It managed to weave one of the most complex, but somehow still cohesive, sci-fi stories we've ever seen." Outside the top ten, Den of Geek named it the 17th best TV show of 2020. Meanwhile, Thrillist ranked it at number 19 on its "40 Best TV Shows of 2020" list, with one of its writers Emma Stefansky calling the series finale "one of the most shocking and emotional conclusions to a TV show you'll see this year."
