In the summer of 1979, gay porn producer Anne sets out to film her most ambitious film yet, but her actors are picked off, one by one, by a mysterious killer.

Two lesbians are victims of a break-in. Together with their clan of friends, they undertake a wild investigation, with suspense and rigour, to arrive at the truth. Sensitivities are aroused around life choices, and political choices. Questions of morality comically embellished with words of abuse falling into drunkenness.

Imagine a slightly dilapidated three star hotel in the tenth arrondissement run by a very distinguished lady with moral fibre and panache, Mrs. Coppercage. Alongside tourists visiting Paris, Mrs. Coppercage rents three rooms to three women at a monthly rate. Each woman is marked by life, yet they go on as best they can, never closing their eyes to the world around them, or to the men who impatiently await them. Faubourg Saint Martin opens as a love story and ends like a song as shots ring out and punctuate the chorus.

This slice-of-life drama about an elderly couple and their estranged son covers twenty-four fateful hours that begin with the usual daily routine for the retired pair of former teachers (Micheline Presle and Claude Pieplu). Then their son telephones to say he will be coming over with his girlfriend and the normal pattern is changed, as he visits them rarely. While the mother is obsequious to her son when he arrives, past hurts and resentments bubble up during lunch, making it difficult for the son to tell them he is getting married. This is news enough, but the effect that announcement has on the son and his fiancée is unexpected and events later on in the day take a turn for the worse.
