Katja Steinfurth tries hard to reconcile her love relationship with her married boss and her obligations as a single mother - not always with success. When Tibor, the favorite horse of her son Lukas, behaves strangely aggressive after an accident and is to be euthanized, the horse whisperer Nils Peterson seems to be the last salvation. So Katja sets off with Lukas and Tibor on the way to the "horse island". And in the seclusion of the small picturesque island, the young woman gradually realizes that something has to change in her life.
