The forces of Paradis begin their assault, but the Warriors stand their ground. As Marley troops close in around them, Eren struggles to break the War Hammer's defenses.

Trapped on the world's most dangerous island, Falco and Gabi will do anything to survive. Elsewhere, the public demands answers when they learn the savior of Paradis has been detained.

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.

Armin and Mikasa speak with Eren, but are astounded by what he says. In the forest, Levi considers feeding the Beast Titan to someone new, but Zeke has other plans in mind.

A look into Zeke's past shows his struggle to become a Warrior. His plans to end the suffering of all Eldians stems from a chance friendship made in his youth.

With the Yeagerists now in charge, Zeke's master plan is revealed. But before it is put in motion, Eren recruits help to flush out any invaders in their midst.

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.

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.

For the flying boat to take off, the mechanics need half a day to service it. Knowing they'll never last that long with Jaegerist reinforcements on the way, the crew is forced to change their plans.

Regardless of where it all began, Eren commits to his path of destruction during the Scouts' first visit to the Marleyan mainland, leaving Mikasa to wonder if things could've been different.

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.
