Frederic (Bernard Verley), deeply in love with his wife Helene (Francoise Verley), lives a monotonous and repetitive life, splitting his time between home and the office, where he always encounters the same people: his partner Gerard (Daniel Ceccaldi) and his two secretaries, Fabienne (Malvina Penne) and Martine (Elisabeth Ferrier). Suddenly, a breath of fresh air arrives in his life: his old friend Chloe (Zouzou), slowly begins to question everything he's ever believed, including his marriage.
