In the seven years that pass, Joe Martin (Charles Bronson) becomes an expatriate living in France. Now married with wife (Liv Ullman) and with stepdaughter, he runs a charter boat, and at the same time one of his former buddies shows up. A fight results and Martin kills the intruder. Unfortunately, the victim is only a vanguard for three new adversaries who make Martin a deadly proposal. It is now Martin’s turn to take the initiative. He kidnaps his adversary Captain Ross’ (James Mason) girlfriend (Jill Ireland), steals his money and stashes both for a trade. The ball is now in Ross’ court and treachery is well within his grasp. Yet a third player appears, unknown to either man.
