It starred Vitti in the lead role, Elliott Gould, Gino Pernice, and Catherine Spaak.

On her birthday, Margherita (Monica Vitti) receives a video camera from a friend, who is a film director (Elliott Gould).

However, on one occasion, Margherita leaves the camera in her bedroom as it was still recording; it catches Margherita's husband, Paolo (Gino Pernice), who has always had a distant demeanor to her, as he cheats on her with her best friend (Catherine Spaak).

A secret scandal ensues in their separation with Paolo's departure and Margherita going into a deep depression, even to the point of contemplating suicide.

Her friend, the director who gave her the camera, examines the film, and concludes that it is interesting material for an actual movie.
