A severed finger and a car with traces of blood: That's all the Bremen commissioners Inga Lürsen (Sabine Postel) and Stedefreund (Oliver Mommsen) find in a parking garage. The owner of the car is the former boss of a pharmaceutical company. According to his wife Judith Bergener (Victoria Fleer), he quit months ago - shortly afterwards his company went bankrupt. The last person who had contact with him was the success-hungry pharmaceutical representative Maria Voss (Nadeshda Brennicke). She wants to "back into the light" at all costs. Stedefreund comes closer to her than Lürsen and BKA colleague Linda Selb (Luise Wolfram) would like.
