When the cautious and clumsy Ulf makes a new friend, his life is turned upside down. Percy is Ulf's complete opposite: he loves to fight, tramples on other people's caps, and everyone avoids him during recess. Ulf desperately wants to be like Percy; he dreams of possessing his magic sneakers, which, according to Percy, grant their owner strength and courage. And he succeeds! But alas, everything is not so simple...

This is a humorous story about how a 'good boy' falls in with bad company and becomes a notorious hooligan. It is based on the true memoirs of the famous Swedish writer Ulf Stark, the author of many books and plays for children.
