Attack on Titans (Movie)
One hundred years ago, the Titans suddenly appeared and decimated most of humanity. To stop their advance, humanity built a series of walls and lived peacefully there for another 100 years. In the present day village of Monzen, Eren expresses to his friends, Armin and Mikasa, his desire to leave the confines of the Outer Wall and see the outside world. After their failed attempt to approach the wall, Souda, the captain of the Garrison, explains to them that the military is assembling a scouting regiment to explore beyond the walls. However, the wall is suddenly attacked by the Colossal Titan. The wall is breached and Titans enter the village, eating people and getting back up despite being injured. When Mikasa tries to rescue a baby, she is separated from Eren, and is presumed killed.
Two years later, Eren and Armin enter the Scout Regiment, along with Sasha, Jean, and others. The team, led by Military Police Commander Kubal, move out into one of the towns of the Outer Wall. The group is then attacked by Titans but are saved by Captain Shikishima and Mikasa, who survived the attack from two years ago and is now part of the Scouts. Eren eventually confronts Mikasa and she reveals to him that the experience made her realize the world is cruel. After realizing that Mikasa and Shikishima are most likely together, Eren is once again devastated.
When more Titans surprise them, Kubal retreats, leaving the Scouts to fend for themselves. Lil, who had just lost her lover, sacrifices herself. Jean attempts to convince Eren to flee, but Eren chooses to fight back before losing his leg in the process. Eren manages to save Armin from being eaten but at the cost of his own life. Though crushed by Eren’s death, Mikasa keeps fighting until she runs low on fuel and comes face to face with the same Titan that ate Eren. However, a Titan emerges from within it and begins battling the other Titans. Souda and Mikasa realize that the Titan is Eren. After he starts to collapse, Mikasa frees Eren from his Titan shell.
