Mankind has retreated behind walls in the wake of the man-eating humanoid giants known as the Titans. After a century of relative peace, a young boy named Eren and his friends Armin and Mikasa venture to the walls edge with hopes of seeing whats on the other side. Then the unthinkable happens: a titan larger and fiercer than any that have been seen before breaches the wall, and titans flood the city. The future looks bleak, but Eren may be humanitys last hope against extinction.
