After a missed call and a disturbing voicemail from his former colleague Hella Christensen, investigator Simon Kessler sets off for Nordholm. The commissioner is aware that something bad must have happened. When Hella's sailing boat is recovered at sea, traces of her blood and her cell phone are found on it, but there is no trace of the former commissioner herself. A SOKO, headed by the new police commissioner Lena Jansen, takes over the investigation. The investigative team not only has to solve Hella's disappearance, but also the death of 15-year-old Viviane, who was found in the woods by her friend Charlotte Broder and probably died of a drug overdose. Kessler realizes how little he knew about the life of his former colleague. After years, Hella's sister Rieke Lehwald suddenly appears with her husband Paul. Do the two have something to do with Hella's disappearance? Is it about an inheritance or a relationship act?

After a missed call and a disturbing voicemail from his former colleague Hella Christensen, investigator Simon Kessler heads to Nordholm to check on her. His instinct tells him something is wrong. Her son Sven and her sister Rieke cannot reach her either. The sisters, who haven't had any contact for years, have a few things to clarify after the death of their father.
After initial problems in Nordholm's police station, Simon Kessler and Commissioner Lena Jansen pull themselves together and investigate together against Thomas Haller and his wife Maria on suspicion of large-scale welfare fraud. There seem to have been falsified accounts for years that nobody noticed - except for Hella, who had an affair with Thomas. Like Hella, the Hallers own a boat with which Thomas often traveled the Baltic Sea. Could he have met her on the open sea? Was he aware that his wife knew about his relationship with Hella?
