Slaughter, a former Green Beret, avenges the killing of loved ones by the Mob, and after being blackmailed by the feds, is forced to head to South America to finish the mobsters off.

Cosmo Vittelli, the proprietor of a sleazy, low-rent Hollywood cabaret, has a real affection for the women who strip in his peepshows and the staff who keep up his dingy establishment. He also has a major gambling problem that has gotten him in trouble before. When Cosmo loses big-time at an underground casino run by mobster Mort, he isn't able to pay up. Mort then offers Cosmo the chance to pay back his debt by knocking off a pesky, Mafia-protected bookie.
