The series is based on the autobiographical novel by Jan Guillou, dedicated to the life of a troubled teenager named Erik. The story takes place in the 1950s. The main character behaves so poorly in class that he is sent to a closed educational institution. The teachers there are quite strict towards the children, and the boy already regularly faces psychological and even physical violence from his stepfather. But it is precisely in the closed school that the main character experiences his first love.
