Ludovic, a 12-year-old boy from a well-off home who is neglected by his parents, who are part of the art scene, falls head over heels in love with Sofie, the daughter of a piano teacher, when he has to pass a test of courage in the schoolyard during recess. The cheeky girl with the two pigtails likes the boy who is interested in her. They soon get closer and meet in secret places in the city. It is the first love for both of them. Shortly after Sofie's father catches the two lovers in bed together in Sofie's room, Ludovic is sent away from Brussels to spend time with his grandparents. But Sofie can't stand it without Ludovic and runs away from home to be with him. The lovers hide in abandoned buildings on the Belgian coast. While parents and police search for the couple, both youngsters find that it is pretty hard to be on their own, especially since an ominous photographer is lurking around the children.
