Two years ago, Paradis welcomed their first visitor who was surprised to see one of their own. Obtaining their help will be critical in a three-part plan to protect Paradis.

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.

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.

The Azumabito's flying boat is guarded by a port full of Jaegerists, but the Scouts are reluctant to kill their former friends. If they wish to avoid bloodshed, they can't afford their plan to go wrong.

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.
