A recently eviscerated bison is found in the forests of Masuria, apparently trapped by skilled poachers. Forensic scientist Dr. Viktoria Wex, who is actually on the way to the train station with the village policeman Leon Pawlak, makes another terrible discovery during the stopover at the site: the body of the shot game warden Glinski, which lies near the carcass! For Viktoria, this is a crime scene that grabs her forensic ambition. What happened here about two hours ago? She decides: your return to Berlin can wait! Although the specialist from Germany lacks any police powers, Leon is just as uninterested in that as inspector Kowalska's instructions to stay away from her work.
