Gabi and Falco seek out a fellow Marleyan who's surprised to see Warrior candidates. The truth of what happened at Ragako may shed some light on Zeke's secret plans.

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.

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.

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.

Deep in the forest, an unlikely rabble of Marley stragglers and island fugitives attempt to set their hatred aside and talk around a campfire without killing each other.

As the rumbling advances, the remaining members of the Scout Regiment race against the clock with their Marleyan and Azumabito allies to catch up to Eren and stop the rumbling before the rest of the world is crushed under the Wall Titans' feet.
