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. Hubert and Staller should also help to give Schmitz a fitting reception, but the two would rather push the case forward. The arrest of Weidinger gives Girwidz hope for a quick solution. But Weidinger does not confess, but claims that he was only looking for his missing cow Emma. With only one arm, he doesn't seem predestined for this murder. The fact that pathologist Anja Licht finds out that the corpse is a young woman who has been strangled doesn't help them at first either. Weidinger must be released. Hubert and Staller have to pick up Police Director Schmitz from the S-Bahn station. There is a momentous accident on the way there - a young man lands on the hood of the patrol car. Driver Hubert is in shock: It looks like the man tried to kill himself by jumping off the bridge and landed directly on her car. Or was there help with the jump? Anja Licht finds traces of blood that do not match the accident. Police advisor Girwidz is on the verge of collapse. Instead of one corpse, they now have two. Police director Schmitz turns out to be a very brazen parasite. And then there is the cow Emma, who, thanks to further traffic obstructions, is now advertised for a manhunt. Hubert and Staller are puzzled and have no idea that the threads come together in a bizarre pensioner flat share on a farm.—ARD Das Erste
