Olga Sundbom is divorced and has custody of her spoiled son Krister. The lack of upbringing has made Krister an intolerable petty gangster. He is therefore put in a boarding school in a smaller town, and his getting in is due to a scam he himself is responsible for. Soon he turns the little idyll upside down.
