Plot

When he was a newborn baby, Edith Guetz thoughtlessly told her son Tanguy : "If you want to, you can stay at home forever."
28 years later, overgraduated student and efficient teacher in Asian languages at the university, this womanizer leads his own successful wealthy life... while still living at his folks' bourgeois place.

For years, Paul Guetz longs to see his son finally emptying the nest ; alas, his desire isn't shared by his wife. But when Edith too can't bear her son's omnipresence anymore, they decide to join their forces making Tanguy's life a living hell. But they don't know that Tanguy isn't the type of guy who gives up too easily...
