Tridan Lagache (Dany Boon) has spent his entire life at Club Med, changing friends every 8 days. At the age of 50, he resigns from the Mexican holiday club, determined to find his childhood sweetheart, Violette, after 42 years. He arrives in Paris, naive and lost but happy to stay with his half-brother, Louis (Kad Merad). To get rid of the burdensome Tridan, Louis begs one of his conquests, Roxane, to impersonate Violette. In this endearing comedy, Charlotte Gainsbourg is irresistibly funny and completes this comedic trio wonderfully.
