Not even at the North Pole is it as cold as in the Paris of this gangster movie. Alain Delon, Gian Maria Volonté and Yves Montand play an unlikely trio: one has just been released from prison, the second has escaped from there, the third is an ex-policeman. In a jewelry store on Place Vendôme, the three want to land the big coup. They are hunted by a grim inspector and the criminal competition.
