Polizeyposchtä Feyf: Police Station 5 in Lucerne celebrates the birthday of their superior Renggli and the return of investigator Lamberti from his three-month leave late into the night. When Lamberti discovers his car missing the next morning, he attempts to find out what happened to it using surveillance camera footage. Unfortunately, however, these images are only of limited use. What can just be seen in the images causes excitement among the team of investigators led by Lamberti and Haas, as they see their superior Renggli being kidnapped by an unknown person in Lamberti's car.
