Caught off guard by Marley's surprise attack, Eren fends off their Titans alone. As the battle rages on above, the Scouts consider Eren's motives from the underground dungeons.

The Beast Titan joins the fray, but General Magath is determined to take him down. Meanwhile, with the city in flames, Colt and Gabi rush to rescue Falco who's held captive by the Yeagerists.

Colt pleads with Zeke to not use his scream and turn Falco into a Titan. All the while, soldiers and Titans clash in battle as Eren struggles to make contact with his brother.

Zeke takes Eren through Grisha's memories to show him how he's been brainwashed. But in doing so, Zeke discovers something about Eren that he never knew.

For 2,000 years, the Founder Ymir has been waiting--a slave to those with royal blood. However, Eren's yearning for freedom gives her a choice that could shake things up.

With no walls left on the island and Shiganshina full of Titans, the Scouts must battle their former comrades. In the midst of it all, Gabi is determined to find and rescue Falco at whatever cost.
