Two Hong Kong cops -- each with a reputation for excessive force -- team up to solve the murders of a prostitute and another policeman. Inspector Kee (Richie Jen) of the narcotics bureau approaches Captain Manfred (Leon Lai) about finding a street thug who lured Kee's partner to his death. Manfred, however, already has his hands full covering up his partner's relationship to a hooker who recently turned up dead. But when it becomes clear both cases are related, the two cops join forces. Wikipedia
