Antoine Beretto, a.k.a. "Tonio", is a former gangster who has retrained in a boat rental, waterskiing and diving school business in
Collioure. Two former accomplices, hunted by the anti-gang brigade, visit him to borrow money and ask him to take them to Italy by sea. Beretto is reluctant at first, but eventually agrees, advancing them four million (40,000 new francs). So that he can get his money back, the two crooks on the run give him the name of Léonard Michalon, a swindler who has vanished with the money from a bet placed at the Cagnes-sur-Mer racecourse. Michalon is a crooked bookmaker. He takes clandestine bets at the races with the promise of huge winnings, but in fact runs off with the money. Antoine Beretto meets Michalon through a friend, Jeff, who, like him, is a retired gangster. Jeff warns him that Michalon is a coward and a traitor. He's a parasite whose profession is to swindle others for pittance. He's not worth the effort, and he's more likely to cause problems than solve them. Once flushed out, Michalon turns out to be just as Jeff describes: passive, whiny, fishy, disloyal and insolvent. But above all, he's wanted by the eccentric gang of the mysterious "Colonel" McLean, a British subject who, suspecting Michalon of knowing about his plans to hold up a huge gold convoy, seems determined to kill him. Antoine and Jeff must do everything in their power to protect Léonard from the colonel's destructive attempts ==Cast==
