Le solitaire

Belmondo as always with his witty expressions, cool and tough attitude and a fight or cascade or two in between, is on the loose after an insane killer back in Paris, two years after the latter killed one of his partners. His ways are not conventional, but it works. Goes after the underworld to get what he wants, however he has to go over the rules of his boss, and has to take care in-between of his former partner's son, an orphan, who has sometimes his ways to keep his guardian off pretty girls...

Worth the watch for French police movie fans...
