Stripes Hinzmann and Leena check on an abandoned truck in the forest, finding a blood trail presumed from the driver fitting stains inside. Forensics concludes a shooting, without trace of victim or killer. Trucker Gerd Paelke was popular in the firm. Boss Fred Tillack's son Torsten, Paelke's sister Yvonne's boyfriend to his stuck-up bossy mother's frustration, has a past in illegal waste disposal, which Paelke's expensive lifestyle suggests he got implicated in as well. The team looks into everyone and gets a crucial, grim clue from the trucking firm's friendly guard dog.
