Events begin to shift into overdrive after the events of "ERASER". While things seem to be going Section 9's way, people in the shadows are starting to appear.

As Motoko, accompanied by her friend Kurutan, arrives at the hospital to switch to a new prosthetic body, Togusa begins the recovery process after being wounded by the DEA's NARC Squad. However, the people still active within the NARC Squad have a few more surprises in store.

A botched arms deal reveals that the government's plans to remove Plutonium from the Shinjuku dig site ("EXCAVATION") by sea have been compromised. Section 9 is called in to take the Plutonium out of Old Tōkyō by land.

The members of Section 9 are not happy being used by the government. Batou is especially incensed since Section 9 is supposed to be an offensive organization. His patience will be further tried when he and Section 9 find out who will be accompanying them on their mission...

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.
