Barnens ö is a Swedish film. The story is set in Stockholm where 11-year-old Reine is on the verge of puberty and afraid of sexual maturity. He lives in a suburb with his single mother who sends him to a traditional Swedish summer camp (common at the time of the setting and managed by the cities for children in need of visiting the countryside. The title of the film is in reference to an island which is home to many such camps). His mother then vacations on her own, but in fact Reine never goes to the camp, instead exploring the summer city of Stockholm on his own, meeting many strange adults.
