Summary Amira has been hired as a cleaner by a cleaning company. Her boss Alex Richmonder is not on good terms with her and threatens her over the phone while she is cleaning up blood residue on a yacht and finding a friend's gold chain. A short time later, Amira is dead. Paul is immediately taken off the ongoing investigation. But he cannot observe this case from a distance. The ex-policeman Richmonder is suspected of the crime. Paul investigates on his own and conceals important details, which not least puts a strain on his private life. When he takes Richmonder to Nele at night, she loses her temper and Mechthild has to perform unusual services. While Nele locks Richmonder up for sinking his gun in the lake, Jakob directs the investigation towards yacht owner Sascha Wiegler. He is having his boat steam cleaned while his dock neighbor Lara Mangold mocks him. But the two have more in common than it initially seems. For Paul, everything is now at stake: his marriage to Christina and his future as a police officer. It's good that Nele has a big heart.
