Jean-Pierre, a soccer agent, has agreed to keep Didier, the dog of friend and film journalist Annabelle. During the night, the Labrador Retriever is transformed into a human, at least in appearance, but Didier is still a dog psychologically. Confronted by Richard, the boss of the soccer club that hires him, Jean-Pierre did not need another problem in addition to the ones from his famous soccer players, Fabrice and Baco, both injured only one week before a very important match against the Paris Saint-Germain. Didier is going to help him and replace the injured players. But the real mission of Didier is to reconcile Jean-Pierre and his girlfriend Maria.
