With the help of Levi's squad, the Recon Corps has successfully captured the Female Titan. As Commander Erwin and Captain Levi begin preparations to extract whoever is inside the Titan, will the Recon Corps discover its true identity, or does the Female Titan have one last trick up its sleeve?

Coupled with the military's cover-up of a previous incident, the shocking discovery inside the Walls causes a stir. Elsewhere, while the new Scout recruits are held for observation, a surprising threat appears.

The Scouts search for a hole in the wall while Eren and the others learn that someone close may be hiding all the answers.

Unarmed and overwhelmed by the Titan assault on the castle, the only hope for the Scouts may lie in a promise and a secret.
