A fairy tale becomes a macabre reality. A series of strange murders puts Jonas Horak, who is in prison for murder, on alert. Policewoman Sophie Landner learns that a highly dangerous serial offender is at work here.
It begins with the murder of a swimmer. A lonely cat is left behind at the edge of the pool. In the sequel to the country crime thriller "The Last Problem", the old fairy tale of the Bremen Town Musicians becomes a terrible reality. Jonas Horak is now imprisoned for murder in an institution for abnormal criminals and is being guarded there. When he learns of the offenses, he suspects something terrible. But he can't be sure yet. Sophie Landner, the policewoman who arrested him, makes a gruesome discovery on a remote farm. The body of a murdered farmer's wife is missing her head. She finds it in a saucepan on the cooker. Meanwhile, a cockerel flutters across the farmyard. Meanwhile, Horak is firmly convinced that the perpetrator of the murders for which he was convicted is back - Friday. No one has ever seen him. He seemed to be a schizophrenic splinter of Horak's sick psyche. Landner visits Horak in prison, who is not very talkative. When Landner speaks to him about Friday, Horak breaks off the conversation completely. The prison warden, who protects Horak as a fine specimen of a psychopath, forbids him to have any further contact with the policewoman. However, Horak finds his worst fears confirmed: Freitag is back and will not rest until he has hunted Horak down for good. A murder with a cat and another with a cockerel? It seems clear to Horak that Freitag is murdering according to the story of the Bremen Town Musicians. He is quite sure that the next murder will have something to do with a donkey. Landner must find it as quickly as possible to prevent the worst from happening.—Arte
