[PART 1] Looking, as latest occupational therapy, for a rare wolf wandered into the region from Italy, Andreas's father Franz Marthaler suddenly finds one, but also the wreck of a crashed sports airplane. Andreas swiftly mobilizes his team, to fly the badly wounded pilot to hospital. Once Toni works out it was Martin Hallinger, transporting a donor heart for his little son Linus Hallinger, and had a young woman aboard, utter hast is required, as the rare fitting heart is good only six more hours. After taking Linus to Emilie Hofer, Andreas gets the boy to confide the mystery passenger is Martin's autistic bastard daughter Laura Weiler. Realizing the wolf must have scared her off, Andreas tracks her down, but her paranoia proves dangerous.
