Возбуждение девушек по вызову (1981) Call-Girls Titillation 1

A prostitute (Brigitte Verbecq) is visited by an old friend (Piotr Stanislas) and they spend a cosy and loving evening together. Outside her flat are two mobsters (unknown man possibly J. Pierre Baccacci, and Dominique St. Clair) discussing that she (Verbecq) is apparently trying to leave their organisation and they suspect him (Stanislas) to be a pimp trying to lure her away. Getting increasingly irate about the matter they decide to burst in and kill him off. However, in the attempt they kill her instead while he manages to escape, with a stolen BMW. (The owner of that car, André Kay, is at the time occupied with banging Elisabeth Buré)...
