Exploitation legend Joe D'Amato, best known for his horror and pornographic films, directs the gritty action movie TOUGH TO KILL (DURI A MORIRE). Martin, a ruthless hit man, joins a group of mercenaries deep in a South American jungle. His plot is to kidnap and collect the million dollar bounty on one of the other hired soldiers during one of their guerilla missions. Unfortunately for him, other members of his squad have the same idea in mind, leading to a series of bloody confrontations in the wilderness. But even as the mercenaries double-cross each other for a piece of the prize, the chance that they will survive the threats of the jungle without each other's help diminishes. TOUGH TO KILL features violent action in the tradition of Italian exploitation films.
