For many years, humanity has been fighting titans — huge creatures that do not have special intelligence, but they eat people and enjoy it. After a long struggle, the remnants of humanity built a high wall surrounding the land of people, through which the Titans could not pass. A hundred years have passed since then, people live peacefully under the protection of the wall. But one day the teenager Eren and his stepsister Mikasa witness a terrible event — a section of the wall is destroyed by a supertitan that appeared right out of thin air. Titans attack the city, and the children are horrified to see one of the monsters eat their mother alive. Eren swears that he will kill all the Titans and avenge humanity.
