A caption explains that under Penal Code 236 a person will be sentenced to a minimum of five years in prison for robbery with the threat of violence.

A caption explains that under Penal Code 199 murderers can receive the death penalty, life in prison, or a minimum sentence of three years.

This makes it impossible to promote Takeshi for the murder and his jail time because he killed the boss of what will now be an affiliated family.

Takeshi secretly travels to Osaka and is picked up from the airport by Tetsu, who has brought the preparations and quickly calls in the "Old Man" from Amagasaki.

These three friends from prison hole up in an unassuming shack, where Takeshi promises that their next heist will bring them a share of ten million yen each.

He explains that he does not want to return to jail so they will not be robbing a bank but rather a location where no police will be called, though he refuses to disclose the target without first getting their agreement to participate.

Takeshi travels to the Ogoto Hot Springs and spies on the meeting between the newly befriended families on the waterfront, identifying an unattended speedboat.

That night the three load the tanks of gas onto the speedboat and ride it to an inn, where Takeshi explains that the two families are now partying following the brotherhood oath ceremony, surely wagering tens of millions of yen on their games.

Disguised in diving gear they then rush into the room where the yakuza are gambling and blast it with tear gas, holding the boss of the Shonankai family at gunpoint while they collect as much money as they can in waterproof bags and run back to their speedboat.

Tetsu and the Old Man look on jealously and ask for 50 million yen more each but Takeshi fights them off, saying that none of the money should be spent in order to avoid drawing attention.

Unable to go to the police, they instead call Bunmei Noshiro, a known crooked cop who has a young fifth wife and needs money.

Noshiro notices some gambling in a local restaurant and threatens to arrest the bookmakers if they don't tell him about any suspicious betting activity lately.

They tell him that Tetsu, who was in jail for three years for robbing a bank, has wagered three million yen recently and they point him out to Noshiro.

Noshiro follows Tetsu to a dance club full of underage hostesses and spots his own young lover Yoko making out with the manager of her old bar, leading to a fistfight.

Noshiro then recognizes Takeshi as the murderer of the old head of the Shonankai family as he collects his million-yen bounty for Tetsu.

Takeshi tells Shizuko that they are splitting up but that he understands why she betrayed him, explaining that he will get a fake passport and take the money abroad.

Bunmei pulls a gun on them but they notify him that he was fired from the police force that day and no longer has protection if he murders them.

Takeshi opens the blinds and begins the bag the money himself and when the Haneda enforcers attempt to stop him they are shot through the window by Bunmei.
