A Vietnam veteran declares a one-man war on crime in this vigilante revenge thriller. Michael Jefferson (Steve James) saved the life of his best friend John Eastland (Robert Ginty) while the two were serving in Vietnam, so when Jefferson is left permanently paralyzed after a vicious attack by muggers, Eastland is determined to get revenge. Declaring war not only on the thugs who injured Jefferson but the entire lawless underclass, Eastland becomes known as "The Exterminator" for his swift and deadly retaliation against muggers and other street criminals. While Eastland's actions may be making for safer streets, they're also illegal, and just as the mob have put a price on Eastland's head, Detective James Dalton (Christopher George) has set his sights on putting "The Exterminator" out of business. Jazz great Stan Getz makes a cameo appearance as himself.
