Olivier (John McEnery) is a wealthy young man with a lively and attractive mother (Valentina Cortese), which is a pity, really, as he can't bear her, or the men she gets involved with. When he gets too upset with her escapades, he begins to break things, or runs off. Otherwise, he spends his time building a boat on the lawn with his friend David (Jean-Pierre Cassal), a poor fisherman whom he grew up with. Though hardly idyllic, the relative calm provided by their friendship is disrupted by Eleonor (Claude Jade), a cute and determined young woman who sets her sights on David. She wants to wean David from his friendship with Olivier and plays on David's long-dormant jealousy of Olivier's wealth and easy life. She also plays the flipside of the jealousy issue, claiming that Olivier has made passes at her.
