A dramatic tale of the moral dilemmas of a not-too-honest cop played out against a background of a manhunt. Pascal supplies his wife, Agnes, with morphine provided by Jaquillat, the local crime boss; Agnes was addicted even before the pair met. But the prison break-out of terrorist Bruno Le Roux, and the certainty that he's settling old scores in the Grenoble area, has made Jaquillat a worried man. He attempts to blackmail Pascal into killing Bruno on sight, using the supply of morphine as a lever. Pascal refuses to co-operate, but he can't tell Agnes why his supplies have suddenly dried up. As a result, she trawls the streets in search of a hit, which is where she meets, and is helped by, the fugitive. He takes her back to her place to tend to her injuries after a street dealer beats her up, and Pascal, coming home, sees them together; however, he doesn't make them aware of his presence, and deliberately lets the fugitive slip through his fingers.
