Every year, Bruno does the wine trail… without setting foot outside the Paris Agricultural Show! But this year, his father Jean, who has come to present his champion bull Nabuchodonosor, in the hope of winning the competition, suddenly decides to take Bruno on a real wine trail, in a bid to become closer with his son. They raise their glasses in Saint-Amour - and would willing raise their glasses to love, too -  accompanied by Mike, a young taxi driver unexpectedly taken along for the ride. Their wine tour is a highly risky venture, combining fine vintages and women encountered along the way.
