Much to the chagrin of Batou, Motoko, and the rest of the team, Kuze and the refugees manage to escape in one of the camouflaged boats. They are further hampered when an explosion causes heavy losses, leaving them unable to follow the fleeing boat.

Regrouping, the team decides to refocus the investigation to the events surrounding Kuze. They start a secret investigation into Sagawa Electronics, the company responsible for the nuclear material transaction, and find that Gouda was involved. Meanwhile, as the boat heads for Dejima, Kuze makes his own unsettling discovery.

Kuze and the Major come up with a plan to save the refugees, but the chances of its success are slim. Realizing this, the Tachikomas disobey the Major's orders and come up with a plan of their own. Batou has also disobeyed the Major's orders to go to the bridge and is desperately searching for her in the ruins of Dejima. Meanwhile, the Prime Minister is frustrated with being spurned by the Chief Cabinet Secretary. Determined to be remembered as more than a mere figurehead, she takes matters into her own hands.
