Desc: Twisted Justice: Directed by David Heavener. With David Heavener, Erik Estrada, Shannon Tweed, David Campbell. In the Los Angeles of the future, police are forbidden to carry weapons and must use stun guns (called "stingers") instead. A maverick detective ignores those restrictions in his pursuit of "The Bullseye Murderer," a psychotic rapist who takes a new drug called "Umbra" that gives him superhuman strength and intelligence.
