The amiable and charming Percy invites himself to join Ulf on his summer holiday on an island in the Swedish archipelago. Though Ulf's parents view Percy as an unsuitable friend for their son, everyone else-including Ulf's curmudgeonly grandfather-appears to love him. But it is too much for Ulf when his summer crush, Pia, also begins to show signs of affection for Percy.
