In the late 1970s, Cockney crime boss Harold Shand, a gangster trying to become a legitimate property mogul, has big plans to get the American Mafia to bankroll his transformation of a derelict area of London into the possible venue for a future Olympic Games. However, a series of bombings targets his empire on the very weekend the Americans are in town. Shand is convinced there is a traitor in his organization, and sets out to eliminate the rat in typically ruthless fashion.

An elite group of vice cops are fired from the L.A.P.D. for being over-zealous in their war against drugs. It is immediately apparent that some of their superiors are involved in the drug ring. Banded together, four of the banned cops (which quickly becomes three when one is killed early) band together to fight the drug ring undercover. They gain capital for weapons by ripping off minor drug dealers. Then well-armed they go after the kingpin (Boyd).
