Overview:The large LKA contingent is searching for a serial killer in Krewlow and hopes to get a clue from the only survivor found on the pile of corpses. However, the seriously injured man is unresponsive. For the village doctor Frank Seeger (Torsten Ranft), it is clear that "Pulver-Paul" (André M. Hennicke) is behind the bloody deeds. The gun-crazy hermit is holed up on his farm and obsessively believes he has to defend himself against overpowering enemies. When Roland Voit (Felix Kramer) and Stanislaw Zajak (Lucas Gregorowicz) want to interrogate him, a life-threatening confrontation ensues. Meanwhile, Maggie (Karoline Schuch) is staying with Adrian Demko (Jan Krauter), her childhood friend who is in a wheelchair. She is convinced that the key to the Oderbruch serial murders lies in their shared past.
