Twelve years later, Griffin — now severely mentally handicapped — is cared for by his younger brother Ash, the leader of a gang of street kids in New York City. One night, Ash encounters a mortally wounded man who gives him a vial of an unknown substance and an address in California; the man utters the words "banana fish" before dying.Ash begins to investigate "banana fish", though he is impeded by Dino Golzine, a Corsican mob boss who had groomed Ash as a sex slave and heir to his criminal empire.

In the course of his investigation, Ash acquires several allies: Eiji Okumura and Shunichi Ibe, who have travelled from Japan to report on street gangs; Shorter Wong, a gang leader who controls Chinatown; and Max Glenreed, whom Ash encounters in prison while detained on a false murder charge. When Griffin is shot and killed in a fight with Golzine's men, the group sets out to solve the mystery of "banana fish" together.Ash and his allies travel to the address in California, finding a mansion occupied by a man revealed to be Yut-Lung Lee, the youngest son of China's largest crime family. They later encounter the home's true occupant, a doctor who informs them that "banana fish" is an untraceable drug that brainwashes its users. Golzine intends to sell the drug to the United States government, which seeks to use it to overthrow communist governments in South America. The group is subsequently captured by Golzine's men, who inject Shorter with banana fish and instruct him to kill Eiji. When Shorter begs Ash to kill him in a moment of lucidity, Ash fatally shoots him.
