A marriage that has fallen on hard times is further tested by the couple’s implication in a murder. Jenny Lamour (Suzy Delair) is a music hall chanteuse married to her pianist husband Maurice (Bernard Blier). Keen to get ahead, Jenny leaps at the chance when an ageing wealthy businessman (Charles Dullin) offers her the chance of some gigs. However, when she agrees to a meeting at his home and he is found dead later in the evening - Maurice’s untamed jealousy is in the frame. A Maigret-esque detective, Antoine, played by Louis Jouvet leaves no stone unturned in his exceedingly private investigations of the down-at-heel showbiz couple’s sad, tempestuous life.
