Nick and Charlie chase and arrest the suspect after he nearly kills Nick. The suspect, a Yakuza gangster named Sato, is to be extradited to Osaka and given to the police there. Though angered Sato will not be prosecuted in the US, Nick agrees to escort him. Nicks captain believes it will keep Nick from causing more trouble and exacerbating the already biased Internal Affairs investigation.When they arrive in Osaka, they surrender Sato to the Japanese police, only to be told that they were duped by impostors. Nick convinces the Osaka police to allow them to observe the investigation, though their weapons are confiscated. They are assigned to Masahiro Matsumoto. Nick behaves rudely and offends Matsumoto, while Charlie attempts to be more polite. Nick also makes contact with an American nightclub hostess, Joyce, who explains that Nick and Charlie represent American inefficiency and stupidity to the Japanese. Through her, Nick discovers Sato is fighting a gang war with a notorious crime boss, Sugai, and traveled to New York to disrupt Sugais counterfeiting scheme. ........
