A different kind of end of work: the patrol car ran out of gas. Hubert and Staller argue on the bus about who is to blame for the dilemma when a cow blocks the road. Hubert drives away the stubborn animal with a warning shot. The bus driver discovers the glow of a fire in the neighboring forest - has the cow fled from it? On site, Hubert and Staller make a gruesome discovery: what burns there are the remains of a person - and the culprit seems to be found quickly: The one-armed farmer Weidinger has hidden in the bushes and is immediately arrested. For Police Officer Girwidz, the gruesome find comes at a very inopportune time. His former supervisor, Police Director Schmitz from Dortmund, surprisingly announced his visit. Girwidz hopes that Schmitz, who is about to retire, is looking for a worthy successor and has already commissioned Sonja and Riedl to bring the area up to scratch.
