A shy young man who commutes between office routine and home comforts, Pierre associates with the opposite sex only in his phantasies. One day he takes a young woman to his room but the anxiety of his repression drives him to murder, In contrast to the act, he calmly disposes of the body so that, upon his mother's return, all is back to normal and life slips back into its pedestrian rhythm. "Decorte uses a modern film style: culously and lasts as long as it would in a real life situation." (Paul Davay, 1978 International Film Guide)
