Early one morning while jogging, Pfefferkorn Malin hears a scream and spots an injured man who appears to have fallen off a building facade. But before she can make out his face, the figure flees, leaving Malin alone to face the police. It turns out that someone has been trying to steal copper pipes. Naturally, the Pfefferkorns want to solve the case, especially since Malin fears the perpetrator might be from her climbing club. However, when she is caught breaking into a locker, she is suspended from training – and feels misunderstood by everyone.
