It’s the story of an unlucky and imaginative boy named Tony and his faithful companion Alberto whom he never leaves! The problem is, Alberto doesn't always know about the nonsense Tony is up to behind his back! Tony uses Alberto as a guinea pig for his delusional experiments, but poor Alberto doesn't necessarily agree! Alberto is a refined dog who prefers reading and quiet games to the insane challenges of his daredevil master. He can also count on his friends Maciste, Jean-Laurent and Fa Dièse to save him from the tyrannical Tony! Tony does, however, have a best friend Robert, who is not very characterful, but he is often accompanied by his sister Clementine, a terrible bad luck charm for Tony!
