[Q]: Five years after the Viking village of Berk and the dragons made peace, they now live together in harmony. Hiccup goes on adventures with his dragon, Toothless, as they discover and map unexplored lands. Now 20 years old, he is being pressed by his father, Stoick the Vast, to succeed him as chieftain, although Hiccup remains unsure if he is ready for this responsibility.
While investigating a burnt forest, Hiccup and Astrid discover the remains of a fort encased in ice and meet a group of dragon trappers led by Eret, who blames them for his fort's destruction and attempts to capture their dragons for an insane conqueror named Drago Bludvist. The two dragon riders escape and return to Berk to warn Stoick about the dragon army that Drago is amassing. Stoick orders the villagers to fortify the island and prepare for battle. Hiccup, however, refuses to believe that war is inevitable. After Stoick interrupts Hiccup's plan to get Eret to take him to Drago, Stoick explains that he once met Drago at a gathering of chiefs, where Drago, mocked after offering the chiefs his service in return for their servitude, murdered them all using armored dragons, with Stoick as the only survivor. Undeterred, Hiccup flies off with Toothless in search of Drago to try to reason with him.
They run into a dragon rider named Valka, who is revealed to be Hiccup's long-lost mother. She explains that she, like her son, could not bring herself to kill dragons. After being carried off during a dragon raid, she spent twenty years rescuing dragons from Drago's traps and bringing them to an island nest created out of ice by a gigantic Alpha dragon called a "Bewilderbeast", which is able to control smaller dragons. Stoick tracks Hiccup to the nest, where he discovers that his wife is still alive. Meanwhile, Astrid and the other riders kidnap Eret to find Drago, but Drago captures them and learns of Berk's dragons.
Drago and his armada lay siege to the nest, where he reveals that he has his own Bewilderbeast to challenge the Alpha. A battle ensues between the two colossal dragons, which ends with Drago's Bewilderbeast killing its opponent and becoming the new Alpha. Drago's Bewilderbeast then seizes control of all the adult dragons, who hypnotically obey. Hiccup tries to persuade Drago to end the violence, but Drago orders him killed. Toothless, under the Bewilderbeast's influence, approaches Hiccup and launches a blast, but Stoick pushes Hiccup out of the way and is hit instead, killing him. The Bewilderbeast momentarily relinquishes control of Toothless, but Hiccup drives him away in a fit of despair. Drago maroons Hiccup and the others on the island and rides Toothless, again under the control of the Bewilderbeast, to lead his army to conquer Berk. Stoick is given a Viking funeral and Hiccup, now having lost both his father and dragon, is unsure what to do. Valka encourages him by telling him that he alone can unite humans and dragons, and inspired by her words and his father's, Hiccup decides to return to Berk to stop Drago.
The dragon riders fly baby dragons back to Berk, as they are immune to the Bewilderbeast's control. They find that Drago has already attacked the village and taken control of its dragons. Hiccup confronts Drago and a brainwashed Toothless while the other riders work to distract the Bewilderbeast. Hiccup succeeds in freeing Toothless from the Bewilderbeast's control, much to Drago's surprise. Hiccup and Toothless briefly separate Drago from the Bewilderbeast and confront Drago on the ground, but the Bewilderbeast attacks them, encasing them in ice. However, Toothless blasts away the ice, revealing that both he and Hiccup are unharmed. He then challenges the Bewilderbeast, shooting it in the face repeatedly, which breaks its control over the other dragons, who now side with Toothless as the new Alpha dragon. All the dragons repeatedly fire at the Bewilderbeast until Toothless fires a final massive blast, breaking its left tusk. Defeated, the Bewilderbeast retreats under the sea with Drago on its back. The Vikings and dragons celebrate their victory and Hiccup is made chieftain of Berk.
Afterwards, Berk undergoes repairs while feeling secure knowing that its dragons can defend it.
[A]: Who does Eret work for?

[Q]: Dean Corso (Johnny Depp), a New York City rare book dealer, makes his living conning people into selling him valuable antique books for a low price, and then re-selling them to private collectors. Corso meets with wealthy book collector Boris Balkan (Frank Langella), who has recently acquired a copy of the (fictional) book The Nine Gates of the Kingdom of Shadows by 17th-century author Aristide Torchia, one of only three extant copies. The book is an adaptation of one written by the Devil himself and purportedly contains the means to summon the Devil and acquire invincibility and immortality. Balkan believes two of the copies are forgeries. He hires Corso to check all three, and acquire the legitimate one by any means necessary.
Balkan's copy was acquired from Andrew Telfer (Willy Holt), who killed himself soon after. Telfer's widow Liana (Lena Olin) seduces Corso, in a failed attempt to get the book back. Meanwhile, Corso leaves the book for safekeeping with bookseller Bernie Rothstein (James Russo), who is then murdered; his corpse is found posed like an engraving in The Nine Gates.
Corso travels to Toledo, Spain. The Ceniza brothers, book restorers, show him that three of the engravings are signed "LCF". Corso deduces that Lucifer himself designed and cut them. Corso travels to Sintra, Portugal, to compare Victor Fargas' (Jack Taylor) copy of the book to Balkan's. To Corso's surprise, he discovers that the signature "LCF" is found in three different engravings, which vary in small but significant details from the images in the Balkan copy. The next morning, a mysterious young woman (identified only as "the Girl") (Emmanuelle Seigner) who appears to have been shadowing Corso since Balkan hired him, awakens Corso and leads him to Fargas' house. He finds the old man murdered and the "LCF"-signed engravings ripped out of that copy.
In Paris, Corso visits the Baroness Kessler (Barbara Jefford), who owns the third copy. At first the Baroness refuses to cooperate, but Corso intrigues her with evidence that the engravings differ among the three copies. He explains his idea: each copy contains three different "LCF"-signed engravings, therefore all three copies are required for the ritual. Corso finds "LCF" on three different engravings in the Baroness's book confirming his theory.
Kessler is killed, and the Girl rescues Corso from Liana's bodyguard. When Liana steals Balkan's copy from Corso's hotel room, he follows her, and witnesses her using the book in a Satanist ceremony. Balkan suddenly interrupts the ceremony, kills Liana, and leaves with the engraved pages and his own intact copy.
Corso pursues Balkan to a remote castle, depicted in one of the engravings, and finds Balkan preparing the final ritual. After a struggle, Balkan traps Corso in a hole in the floor. Balkan performs his summoning ritual: he arranges the engravings on a makeshift altar, and recites a series of phrases related to each of the nine engravings. Balkan then douses the floor and himself with gasoline and sets it alight, believing himself to be immune to suffering. Balkan's invocation fails, and he screams in pain as the flames engulf him. Corso frees himself, kills Balkan, takes the engravings, and escapes.
Outside, the Girl appears and has sex with him by the light of the burning castle. She tells him that Balkan failed because the ninth engraving he had used was a forgery. On her suggestion, Corso returns to the Ceniza brothers' now vacant shop. By chance he finds the authentic ninth engraving. On it, there is a likeness of the Girl. With the last engraving in hand, Corso returns to the castle. He has completed the ritual requirements, and he crosses through the Ninth Gate into the light.
[A]: What is so special about the ninth engraving?

[Q]: The story may not be linear and exhibits several instances of temporal disruption. A dark-haired woman (Harring) escapes her own murder, surviving a car accident on Mulholland Drive. Injured and in shock, she descends into Los Angeles and sneaks into an apartment that an older, red-headed woman has just vacated. An aspiring actress named Betty Elms (Watts) arrives at the same apartment and finds the dark-haired woman confused, not knowing her own name. The dark-haired woman assumes the name "Rita" after seeing a poster for the film Gilda (1946), starring Rita Hayworth. To help Rita remember her identity, Betty looks in Rita's purse, where she finds a large amount of money and an unusual blue key.
In what seems to be a scene from a different narrative, set at a diner called Winkies, a man (Patrick Fischler) tells his companion (Michael Cooke) about a nightmare in which he dreamt there was a horrible figure behind the diner. When they investigate, the figure appears, causing the man with the nightmare to collapse in fright. As the principal narrative resumes, Hollywood director Adam Kesher (Justin Theroux) has his film commandeered by apparent mobsters, who insist he cast an unknown actress named Camilla Rhodes (Melissa George) as the lead in his film. After he resists, he returns home to find his wife having an affair and is thrown out of his house. He later learns that his bank has closed his line of credit and he is broke. He agrees to meet a mysterious figure called The Cowboy, who urges him to cast Camilla Rhodes for his own good. Later, a bungling hit man (Mark Pellegrino) attempts to steal a book full of phone numbers and leaves three people dead.
Trying to learn more about Rita's accident, Betty and Rita go to Winkies and are served by a waitress named Diane, which causes Rita to remember the name "Diane Selwyn". They find Diane Selwyn in the phone book and call her, but she does not answer. Betty goes to an audition, where her performance is highly praised. A casting agent takes her to the set of a film called The Sylvia North Story, directed by Adam, where Camilla Rhodes gives an audition and Adam declares, "This is the girl." Betty smiles shyly as she locks eyes with Adam, but she flees before she can meet him, saying that she is late to meet a friend.
Betty and Rita go to Diane Selwyn's apartment and break in when no one answers the door. In the bedroom they find the body of a woman who has been dead for several days. Terrified, they return to their apartment, where Rita disguises herself with a blonde wig. The two women have sex that night and awake at 2 a.m., when Rita insists they go to an eerie theater called Club Silencio. On stage, a man explains in several languages that everything is an illusion; a woman begins singing then collapses, although her vocals continue. Betty finds a blue box in her purse that matches Rita's key. Upon returning to the apartment, Rita retrieves the key and finds that Betty has disappeared. Rita unlocks the box, and it falls to the floor with a thump.
The older red-headed woman investigates the sound, but nothing is there. The Cowboy appears in the doorway of Diane Selwyn's bedroom saying, "Hey, pretty girl. Time to wake up." At this point, all elements of the narrative seem to change. Diane Selwyn (played by Watts) wakes up in her bed. She looks exactly like Betty, but is portrayed as a failed actress driven into a deep depression by her unrequited love for Camilla Rhodes (played now by Harring). On Camilla's invitation, Diane attends a party at Adam's house on Mulholland Drive. Her limousine stops before they reach the house and Camilla escorts her using a shortcut. Adam appears to be in love with Camilla. Over dinner, Diane states that she came to Hollywood when her aunt died, and she met Camilla at an audition for The Sylvia North Story. Another woman (played by George) kisses Camilla and they turn and smile at Diane. Adam and Camilla prepare to make an important announcement, and dissolve into laughter and kiss while Diane watches, crying.
Diane meets with the hit man at Winkies, where she gives him Camilla's photo and a large amount of money, and they are served by a waitress named Betty. The hit man tells Diane that when the job is done, she will find a blue key. Diane asks what, if anything, the key opens, but the hit man just laughs. Diane looks up and sees the man who had the nightmare standing at the counter. Back at her apartment, with the key on a table in front of her, she is terrorized by hallucinations. She runs screaming to her bed, where she shoots herself. A woman at the club whispers "Silencio".
