Detective Chief Inspector Tom Engelhardt and his team have solved a double murder on the Darß, but they are not one step closer to the unknown man who killed an entire family on a sailing yacht. Cryptologist Mascha Krieger and her brother Holger have also not yet caught the murderer of the young doctor from Anklam. Meanwhile, Detective Chief Inspector Björn André from Teterow investigates an alleged case of suicide. A young woman has cut her wrists, but the circumstances are strange. Björn comes across a letter, very similar to the one the doctor from Anklam received on the day of her death. When such a letter also appears on the Darß, it is clear that all crimes must be connected. A large Soko is formed under the leadership of Tom Engelhardt. And there is already a suspect: Hagen Oltmanns, a homeless man living in the forest who not only owns a box full of weapons, but also suffers from paranoid schizophrenia. But Oltmanns has disappeared without a trace. Then another body is found. And suddenly the investigation turns in a completely unexpected direction.
