Pierre Rossi and Béatrice live in the same block of flats in Marseille and love each other. One night, Béatrice leaves her apartment. Pierre knows that his fiancée goes to a rendezvous, but she would not tell him more than just that. Worried, Pierre follows her but he is attacked and stolen his identity papers by two men, Tom and Nasol, on the payroll of Quaglio, one of the city's bosses. Later on, Quaglio kills Nasol and deposits the body in a garage, leaving Pierre's papers nearby. As for Pierre, he manages to follow Tom to a villa where several young women have been invited. Pierre, horrified, realizes that this place is the headquarters for the white slave trade. - Written by Guy Bellinger
