In this rollicking and earthy French comedy, a wayward moonbeam transforms a golden retriever into an ace soccer player thus saving his latest master. Technically, doggy Didier belongs to Annabelle, a scatterbrained international journalist. While she is away on assignment, she remands him to the temporary custody of her pal Costa who is not happy to have a new burden on his already high-pressure life. He is the manager of a soccer club that has been doing poorly since his star player was injured and benched. The irate club owner has sent his personal goons out to force Costa into finding a replacement before the upcoming big game. That coupled with the fact that his girlfriend has just dumped him, has put Costa in a sour mood. Now he must care for a slobbery dog? Then the moonbeam works its magic and Didier becomes a human. At first he is utterly clueless and Costa must teach him everything, but when ever-loyal Didier proves to have real talent with a soccer ball, Costa sees light at the end of the tunnel.
