Charles Bronson stars as Joe Moran, an ex-con and former drug dealer, who's forced back into the narcotics trade after his wife is kidnapped by a powerful drug lord. In order to save his wife and seek his violent revenge, Moran must fight the ruthless gang -- alone.
In the seven years that pass, Charles Bronson becomes an expatriate living in France. Now married, with wife (Liv Ullman) and stepdaughter, he runs a charter boat and at the same time one of his former buddies shows up. A fight ensues and Bronson kills the intruder. Unfortunately, the victim is only a vanguard for three new adversaries who make Bronson a deadly proposal. It is now Bronson‘s turn to take the initiative. He kidnaps his adversaries (James Mason) girlfriend (Jill Ireland), steals his money, and stashes both for a trade. The ball is now in Mason‘s court and treachery is well within his grasp. Yet, a third player appears unbeknownst to either man; an adversary both develop a chilling "Cold Sweat" over.
