Jean-Pierre Melville, France, Italy, 1967o
After the murder of a jazz club owner, hit man Jef Costello is arrested by the police during a raid. But the main witness to the murder, who clearly recognized the killer, covers for Costello. He is released but continues to be shadowed. His unwanted proximity to the police makes him a danger to the person who ordered the murder, who now wants Costello's life himself. Little by little, the net tightens around the silent killer.
