Tridan Lagache has spent his whole life at Club Med, changing friends every 8 days. At 50, he resigns from the Mexican vacation spot where he was born, bound and determined to seek out his great childhood love, Violette, 42 years later. Naive and clueless, he shows up in Paris and is thrilled to stay at the home of Louis, the half-brother he never knew he had. Tridan is the last thing Louis needed, so he begs Roxane, one of his conquests, to pass herself off as Violette. One glance at Roxane, and Tridan is certain he has found his long lost soul mate.
