In the fourth recap movie, episodes 1-59 of the anime are retold, compiling the first three seasons of the anime into one two hour event.
Eren Yeager and others of the 104th Training Corps have just begun to become full members of the Survey Corps. As they ready themselves to face the Titans once again, their preparations are interrupted by the invasion of Wall Rose—but all is not as it seems as more mysteries are unraveled. As the Survey Corps races to save the wall, they uncover more about the invading Titans and the dark secrets of their own members.
100 years ago, titans suddenly appeared on Earth. Soon, human civilization veered on collapse due to the titans. Humans then built a giant wall to defend themselves. Within the giant walls, humans lived in peace, but, 100 years later, the giant wall is broken.
Recap of episodes 14-25.
Recap of episodes 1-13.
Eren leaves to restore a break in the wall destroyed by a Titan. He comes under attack by the Titans and is cornered. Shikishima comes to his aid. The titans never stops attacking. Eren is now injured and tries to protect Armin, but is swallowed by a titan. A Titan with black hair appears and begins to expel the other titans.
Several hundred years ago, humans were nearly exterminated by Titans. Titans are typically several stories tall, seem to have no intelligence, devour human beings and, worst of all, seem to do it for the pleasure rather than as a food source. A small percentage of humanity survived by walling themselves in a city protected by extremely high walls, even taller than the biggest Titans. Flash forward to the present and the city has not seen a Titan in over 100 years. Teenage boy Eren and his foster sister Mikasa witness something horrific as the city walls are destroyed by a Colossal Titan that appears out of thin air. As the smaller Titans flood the city, the two kids watch in horror as their mother is eaten alive. Eren vows that he will murder every single Titan and take revenge for all of mankind.
The story follows Eren Yeager and Mikasa Ackerman entering Titan Jr. High, a school where humans and Titans study in the same area in coexistence. Because of a "traumatic" event, where the Colossal Titan ate his lunch back in middle school, Eren hates the Titans, and is constantly trying to find a way to rid the earth of their kind. Because of this, he has a hard time making friends, much to Mikasa's worry.
During the Great Titan War, a race of giants called Titans nearly wiped out humanity. The survivors built three concentric walls tall enough to keep the Titans out, but a century into that era of peace, the Colossal Titan suddenly appeared and kicked a hole through the Outer Wall, allowing other Titans to surge through. Forced to retreat behind the Middle Wall, humanity begins planning its retaliation.
