Les confidences de Sandra (1973)

In Saint-Tropez, Sandra leads an easy life and enjoys great freedom. But at the end of the summer, she is obliged to return to Paris, where she has to work in a brothel to earn a living. Far from the idleness of the coast, she multiplies the encounters with men who wish to be accompanied by pretty girls. The appointments follow one another but are not alike for her. One day, she witnesses a murder in the house of rendezvous which employs her. As a single witness to the drama, she is soon questioned by the police, who knows her call girl activities. Being wary of police, she flees away without further delay.
