Obsessed NYC cop Tony Luca (Biehn) tries to bring down crimelord Rocco (Stark) but things go badly and instead he's taken off the case. His new assignment is investigating yakuza murders in Little Tokyo, which has also drawn the unwanted attention of South Korean detective Kim (Park), who recognizes the killer's MO. But when mobsters also start dying it turns out the bad guy is trying to get rid of the mob and the yakuza and take over.
