Ostfriesennacht

A murderer is on the loose in East Frisia. One who kills women in vacation homes. They all have one thing in common: they all had a tattoo of a so-called power animal, which has been removed and is nowhere to be found at the crime scenes. Is the murderer keeping the artwork as a trophy or does he have other plans for it?
While Rupert uses his private contacts to lure the main suspect out of the reserve beyond official investigation methods, Ann Kathrin Klaasen tries to save her husband Frank Weller from disaster.
He has a bad feeling because his daughter has a new boyfriend, an old acquaintance whom he deeply dislikes. When his daughter also gets such a tattoo, Weller digs deeper. And he finds what he is looking for! The new lover could well be the psychopathic serial killer he is looking for. Even though Jule declares her father to be paranoid and Ann is also skeptical, he is firmly convinced that he has to rescue his daughter from the clutches of a serial killer. He risks everything to do so and his relationship with his daughter is put to the test. To make matters worse, the BKA also gets involved, because the series of murders didn’t just start in East Frisia…
