This time, Leon Schuster plays a filmmaker who is making a candid camera movie, only to discover that another filmmaker has stolen his ideas and is making the identical picture. How so? It seems that the thieving rival is blackmailing Schuster´s girlfriend. With the help of his friends and an ingenious talking cap that he designed himself, the good director manages to outwit the baddie, get the girl and make the country laugh.

The film takes place during the annual Rapport International Cycling Tour. Two brothers compete as Cain and Abel against each other. Not only for the coveted trophy, but also a girl who stole both hearts. A young champion must learn overnight to accept the harsh reality of adult life.
