The Goodbye Singing(1977)

Original title: Le Chant du départ

In her suburban house, Madame Vaussart brings together a group of solitaries every Wednesday. Everyone tries to forget their problems, their complexes, their sadness. Between Mr. Michel, very shy, Mrs. Lebris, a former actress, a former colonial soldier and a few others, a project was soon born. They arm themselves and organize a manhunt from which, voluntarily, no one will come out alive.
