In this French fantasy-comedy, a magical moonbeam turns a dog into a man's best friend. Annabelle (Caroline Cellier) is a reporter who is sent on an overseas assignment and doesn't think it would be such a great idea to bring Didier, her Golden Retriever, along, so she leaves the pooch in the care of her friend Costa (Jean-Pierre Bacri). Costa is less than excited about being handed dogsitting duties, since he has enough on his mind as it is; he's the coach of a soccer team that has been playing poorly since their star player was sidelined with an injury, and his girlfriend has just given him his walking papers. But one evening a moonbeam glides over Didier, and suddenly the dog is magically transformed into a man (played by Alain Chabat), as luck would have it for Costa, a man who happens to be a really great soccer player.
