Eren Jaeger, of the town called the Shiganshina District, wishes to see the outside world by joining the Scout Regiment, as he likens living in the cities to being like livestock. His resolve impresses his father Grisha Jaeger, who promises to show him what lies in their basement once he returns. Things change when the Colossal Titan, a giant 60-meter Titan taller than regular ones, appears and destroys the gate, allowing smaller Titans to enter. As the town erupts into mass panic, Eren and his friend Mikasa Ackerman find Eren's mother Carla Jaeger pinned under their collapsed house. A Smiling Titan approaches and Carla begs them to flee.

Eren has a strange dream in which his grieving father forcefully gives him an injection and a key. Angry and bitter, Eren grows disgusted with the people of Wall Rose when they show disdain for sharing their food and resources with the refugees. During the next year, as a food shortage becomes apparent, the government sends about 250,000 refugees, 20% of the populace, to fight to reclaim Wall Maria, only to be wiped out by the Titans.

The recruits train on an omni-directional mobility gear apparatus, where they have to balance themselves while suspended on cables. After Eren has trouble balancing, he asks Reiner Braun and Bertholdt Hoover for help and learns that they, like him, are among the few who have personally encountered Titans.

They are eligible to join the cushy Military Police Regiment, but Eren joins the Scout Regiment on the front lines, leading Armin and Mikasa to join him, though he tries to dissuade them.

| The Colossal Titan vanishes in a burst of steam before Eren can attack. The Military Police Regiment scrambles to evacuate the people of the Trost District and set up defenses.

In the chaos, Eren and Armin's comrades are killed or eaten by the Titans, with Eren himself losing his left leg when he attacks in haste. Armin, paralyzed with fear, is picked up by a Bearded Titan.

Mikasa kills it with her atypical, powerful prowess, saving everyone. A flashback to the year 844, a year before the fall of Wall Maria, shows that Mikasa's family was targeted by three slave traders, who murdered her parents. Grisha and Eren discovered the corpses during a visit and Eren tracked down the slave traders to a nearby hut and killed two of them to save Mikasa. The third slave trader began strangling him. Encouraged by Eren, Mikasa overcame her fear and gained resolve to kill the slave trader. Grisha took Mikasa in, and she now considers the Jaegers family. |||||||

Mikasa learns from Armin that Eren is dead. She rallies the others to reclaim the supply depot by taking down the Titans but runs out of gas and falls into an alley. Jean assumes command, but loses his nerve momentarily when he sees his comrades being eaten. He eventually makes a judgement call, leading his surviving team members to headquarters. As a Titan approaches Mikasa, a mysterious, black-haired Titan appears and brutally kills it, much to her confusion. Armin, Conny, and Mikasa are shocked to witness the mysterious Titan not only fighting other Titans, but showing knowledge of their weak point and using hand-to-hand combat, while ignoring the humans.

| With the supply depot swarming with Titans, Armin has the idea of luring the mysterious Titan there to defeat them. His plan works, but while the mysterious Titan is able to kill the enemy Titans outside, seven smaller Titans are in the fuel storage area. With their equipment out of fuel, Armin devises another plan. The survivors shoot the Titans in the eyes to blind them, while seven others jump to finish them off. This, too, is successful and having replenished their fuel, the soldiers prepare to retreat.

| Captain Levi of the Scout Regiment and his squad are on a mission retaking a town from the Titans, but are called to the Trost District when the Titans invade. When Eren was swallowed alive by the Bearded Titan, he found himself in its stomach with the bodies of its victims. His rage at the Titans caused him to burst out of the Bearded Titan's stomach by transforming into a Titan himself and going on a rampage. Eren's comrades, who witnessed him emerge, agree to keep it a secret; however, Kitts also witnessed him and hysterically orders the cannons to fire on Eren, and Armin and Mikasa, who are shielding him. Eren recalls memories of his father giving him an injection to make him lose his memories, telling him the key around his neck will help him remember, and that he must go to their home's basement with the key, as the information they need is there. Eren remembers how to transform—by biting his hand—and protects his friends from the explosion by partially transforming into a Titan, sheltering them inside his ribs. |||||||

| Eren detaches himself from his Titan's body and climbs out, telling Mikasa and Armin about the basement in his old, destroyed house. His father was working on a secret project there and he believes that it holds the secret to mankind's preservation and destroying the Titans. As the cannons are reloaded for another attack, Eren comes up with two escape plans. The first is for him to flee as a Titan and journey to his old house but criminalize himself, and the second is to have Armin convince Kitts that he is an asset to humanity and the military rather than a danger. Armin decides on the second. However, Kitts is overcome by fear and gives the order to fire. As the trio prepares to defend themselves, the order is halted by Commander Dot Pyxis, as he wants to hear Armin out. Pyxis guarantees their safety in return for Eren's Titan to block the destroyed gate in Wall Rose to prevent more Titans from getting in. Eren agrees to try, regardless of whether or not he will be able to. |||||||

| As Armin helps Pyxis's subordinates coordinate a plan, morale among the troops begin to drop at the thought of facing the Titans again. Pyxis reminds them that if they abandon their posts, they will be subjecting their families to the same terror they faced; this convinces the troops to stay. Claiming that Eren is the result of a secret project to turn humans into Titans, Pyxis plans to have most of the troops gather at a far corner of the Trost District to lure most of the Titans away while Eren as a Titan is posted on the opposite end to carry the giant boulder to seal the hole. Eren will be guarded during the mission by three of the best elites of the Garrison Regiment; Ian Dietrich, Rico Brzenska and Mitabi Jarnach, with Mikasa joining for her extraordinary skill. Reaching the boulder, Eren transforms into a Titan, only to turn and attack Mikasa. |||||||

| Mikasa tries to reason with Eren's Titan form, but to no avail. He accidentally incapacitates himself, slumping to the ground. The elite squad protecting him sends up a red flare to signal that the plan has failed, to the dismay of the rest of the troops. As Armin heads toward Eren to investigate, the elite squad argues about withdrawing and abandoning him to the Titans but Captain Ian convinces them to protect him even while he is incapacitated, recognizing Eren's potential as a valuable asset. Jean's mobility gear malfunctions, forcing him to hide from Titans. Armin reaches the unconscious Eren and plunges his sword into the Titan's left arm, which briefly awakens Eren from the pain. As Armin speaks to him of their dream to see the outside world and his promise to kill all Titans, Eren leaves his dreamlike state and regains control. |||||||

| Jean escapes with Annie, Connie and Marco Bott's help. To everyone's surprise, Eren in his Titan form starts carrying the boulder toward the gate. Captain Ian orders everyone to protect him. As the soldiers fight off the Titans, Eren successfully blocks the gate. Rico fires a yellow flare to signal that the operation was a success. When Armin and Eren are cornered by two Titans, Levi saves them just in time. In the aftermath, all Titans remaining in the Trost District are eliminated and two are captured for research. The troops mourn the deaths of their comrades among the casualties incurred. Eren is chained in a jail cell guarded by the Military Police Regiment, where he is visited by Levi and Commander Erwin Smith of the Scout Regiment, who now hold Eren's key. Eren tells them about the basement; upon hearing that he wants to join the Scouts, Levi takes him into his squad, stating that he will take responsibility for Eren, but warns that he will kill him if Eren ever loses control. |||||||

| The populace is divided over whether Eren is their savior or their end. He is brought to a military tribunal where Commander-in-Chief Dhalis Zachary will decide whether he should be handed over to the Military Police Regiment or the Scout Regiment. The Military Police wants Eren executed, seeing him as a danger, while the Scout Regiment wants to use his ability to retake Wall Maria. Eren angrily calls out the Military Police for their cowardice and selfishness. Levi brutally beats him in retaliation; despite his anger, Eren does not transform as feared. Levi and Erwin use this to show that the Scouts can control him and kill him if need be. Thus, Zachary gives him to the Scout Regiment. Erwin and Levi make amends with Eren for beating him up, though Eren understands it was necessary to get him under the Scouts' supervision. As he is getting treatment, they are bewildered to see that the tooth Levi knocked out has already grown back. |||||||

| Levi and his Special Operations Squad, composed of Eld Gin, Oruo Bozad, Petra Rall and Günther Schultz, bring Eren to the old Scout Regiment headquarters, where he will learn to control his Titan powers under their watch. Erwin and Miche Zacharius discuss how they must prove Eren's usefulness to the Military within a month but Erwin hints that there is another reason for Eren's presence and the upcoming expedition. Hange asks Eren to help in experiments with the two Titans they've captured, which Hange named Sawney and Beane. It is revealed that Titans need sunlight to survive and their bodies are disproportionately light despite their size. The next day, the Scout Regiment discovers that Sawney and Beane have been killed and the culprit is likely a soldier themselves, which makes Eren wonder who their true enemy is. |||||||

| As the recruits are investigated over Sawney and Beane's deaths, Annie joins the Military Police Regiment. The 104th class of cadets are greeted by Erwin at the Decision Ceremony, where he informs them that the goal of the Scout Regiment's expedition next month is to reclaim Wall Maria so they can enter the Shiganshina District and uncover the secret in the basement of Eren's home. He tells them of the Scout Regiment's high mortality rate, since they are the military branch responsible for outside exploration and Titan combat. After hearing of this, most recruits leave to join the other branches. Jean, suffering from guilt and inner turmoil, joins the Scouts in honor of Marco; Mikasa, Armin, Reiner, Bertholdt, Conny, Sasha, Christa and Ymir also join. Thus, Eren is reunited with his friends after a while. The Scout Regiment embarks on their 57th Expedition beyond the walls. |||||||

| As they begin the 57th Expedition, the Scout Regiment assembles into their Long-Range Scouting Formation, wherein they spread out in a semicircle around the main wagon train and signal by colored flare guns if Titans are nearby so the group can collectively alter course to avoid conflict if possible. Things get difficult when a Female Titan suddenly appears at high speed toward Armin's squad. Much to Armin's shock, this Titan is intelligent enough to kill his seniors and protect her neck. She captures Armin, but after seeing his face, inexplicably lets him go, causing Armin to realize that she is possibly a human with a Titan form like Eren. Armin is picked up by Reiner and Jean, who reveal that their right flank was wiped out by Titans. They realize that the Female Titan's target is Eren and try to stop her but fail. |||||||

| Armin, Reiner and Jean are left with only one horse after their encounter with the Female Titan. They are saved when Christa arrives with extra horses. To everyone's surprise, the operation is continuing, albeit heading in a different direction. News reaches the center group about the annihilation of their right flank by the Female Titan. The formation breaks entirely as the Scouts all reach the Forest of Giant Trees; only the center row enters while the rest defend the forest from Titans. Eren realizes something is wrong when he sees that no one in his squad has any idea of what they're doing or what Erwin's plan is, including Levi. As the Female Titan arrives at their heels, Levi tells his squad to cover their ears, preparing his flare gun. |||||||

| Levi fires a noise round and tells the squad to keep moving forward. With more of the rearguard being killed by the Female Titan, Eren begs his squad to let him fight, but they tell him to trust Levi's decision. Eren recalls when he was unable to transform into a Titan for experimental purposes for Hange and the squad. During a break, when he tried to pick up a fallen teaspoon, he unexpectedly partially transformed, leading the squad to panic and Hange to deduce that he is able to transform not by simply injuring himself but also when he has a specific goal in mind. The squad later apologized to Eren, telling him they should trust each other. Eren decides to trust in the current plan. It is revealed that Levi's squad is bait to lure the Female Titan into an ambush in the forest, where Erwin and his men fire hundreds of grappling hooks to trap her. Levi leaves to meet with Erwin to determine next steps. |||||||

| Though the Female Titan is restrained, the squad is unable to extract the human inside as she is able to crystallize her skin to prevent them from cutting her skin. Everyone realizes it was Erwin's plan to use Eren as bait to draw out the mole within the army who joined them after the Walls fell; that's why he kept the plan from all current members and only revealed it to those who were part of the Scout Regiment before the fall. The Female Titan suddenly hollers a scream that draws all Titans in the vicinity towards her. Despite the Scout's attempt to stop them, the Titans ignore them and eat the Female Titan's body in a frenzy. Thus, Erwin calls off the expedition. With no confirmation that the mole inside has also been eaten, Erwin orders Levi to replenish his gas and gear just in case before returning to his squad. The mole is indeed alive; disguised as a cloaked Scout Regiment member, they attack Levi's squad and kill Günther. |||||||

| Erwin realizes it was a mistake to think that all intelligent Titans are like Eren, since the Female Titan has abilities far beyond that of a novice. The mole once again transforms into the Female Titan and chases after Levi's squad. Armin theorizes that the mole is someone who had seen Eren transform during the invasion of the Trost District. Eren wants to transform but the squad tells him to trust in their skills to protect him. Eld, Oruo, and Petra manage to blind the Titan; however, she regenerates her right eye and kills all three of them. Grieving and furious, Eren transforms into a Titan. Believing his squad's death could have been avoided if he'd transformed in the first place, he fights the Titan but she defeats him by beheading him and swallowing his human body. Mikasa attempts to intervene, but to no avail. Levi arrives, telling her to keep her distance, as the Female Titan is getting tired and they can take advantage. |||||||

| Levi debilitates the Female Titan at incredibly high speed so that she can't even crystallize her skin in time. He injures his leg when saving Mikasa but is able to retrieve Eren from the Female Titan's mouth, as she is now badly wounded and slumped against a tree. The Scout Regiment somberly retrieve the corpses of their fallen and begin the journey home. On the way, they are chased by two Titans. One is killed by Mikasa and they outrun the second after Levi orders them to dispose of the corpses to lighten the wagon's load. Eren wakes up and finds that they are back in town behind Wall Sina. The townspeople not only berate the Scout Regiment's ineptitude but are enraged over the casualties. As a result of the failed expedition, Erwin and his subordinates are summoned to the capital, where Eren is ordered to be handed over. |||||||

| In the Stohess District, the Military Police Regiment are ordered to escort the Scout Regiment convoy once they enter the capital. Annie's colleagues Hitch Dreyse and Marlo Sand are in the Military Police for opposite reasons, one for its corruption, the other for its reformation. After the convoy has entered, Armin secretly calls Annie away and begs for her help in smuggling Eren out of the capital so the Scout Regiment has time to gather proof to keep him. The one riding in the convoy is Jean in disguise. Annie agrees and Armin brings her, Eren, and Mikasa to a tunnel. Annie refuses to enter and realizes that she has walked into a trap, surrounded by Scouts. Armin finally reveals his suspicion that Annie is the Female Titan; she used Marco's omni-directional mobility gear to kill Sawney and Beane and did not kill him during the 57th Expedition. They beg Annie to prove them wrong she laughs and transforms by wounding her hand with the spike in her ring. |||||||

| A few days earlier, Eren was informed by Erwin that Annie was suspected to be the Female Titan, thanks to Armin's deductions, and how they plan to capture her. In the present, Eren tries to transform but is unable to as his feelings for Annie are holding him back—he is unable to accept that someone he trusted turned out to be the Titan. He is then heavily injured from a tunnel collapse. Commander Nile Dawk of the Military Police Regiment demands an explanation from Erwin, holding him at gunpoint and threatening him of treason. As the Scouts tries to capture Annie, Armin tells Eren that those who cannot sacrifice anything can never change anything; Mikasa reminds him that they live in a cruel world and must fight. Eren remembers his squad's deaths and his mother's, and uses his intense hatred of the Titans to finally transform. |||||||

| A group of worshippers who idolise the Walls are ironically crushed by Annie, leaving Minister Nick the only survivor. Eren and Annie fight in their Titan forms throughout the Stohess District, causing destruction and civilian deaths. As this was Erwin's operation, he accepts responsibility for the damage and is arrested by Nile. Annie is overpowered and attempts to escape by climbing up Wall Sina, but Mikasa cuts off her fingers. Eren prepares to eat the human Annie but Levi stops him as she must be captured alive for interrogation. Annie's body encases itself in crystal, leaving her comatose and safe from interrogation. Erwin attends a government inquiry to clear his name, explaining that despite the deaths, he believes the operation was a step forward for humanity; they now plan to hunt down more intelligent Titans and launch a counterattack. Eren remains with the Scouts, who have Annie's custody as well. In the epilogue, a piece of Wall Sina crumbles, revealing the face of a Titan buried inside. |||||||
