A special military tribunal will decide Eren's fate. The Military Police calls for his execution while the Recon Corps argues that he is a powerful resource for humankind, and Mikasa is put on the spot when asked about the events of the Trost mission.

The Recon Corps moves Eren to an old abandoned castle where he will continue his training. Hange visits and reveals that she's been putting two captured Titans through a series of tests and trials — experiments that she wants Eren's help with.

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?

Hange is insistent on capturing a Titan for the advancement of scientific research, but Erwin is adamant in his refusal to allow it. Will an unexpected discovery during an expedition beyond the walls alter the situation?

Levi and his crew steal from merchants to scrape by in the dreary Underground. They're approached by a man from the surface with a job that could change their lives for the better.

Levi's group joins the Scout Regiment, but they bring with them a hidden agenda. The upcoming expedition beyond the walls seems like the perfect opportunity to carry out their plan.

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.
