Three events that seemingly nothing related, namely the murder of a truck driver, the discovery of the corpse of a vitriolic young woman, and the death of another who was crushed, will launch the Inspector Maréchal on the trail of a prostitution network. The girl-mother Olga, a friend of the trucker, confesses her the underwear of the women's exploitation.
