The young and attractive police inspector Lola Kraft loses her partner during a botched operation in Stuttgart and is subsequently transferred to the supposedly quiet town of Calw as a form of punishment. But right away in her first case, which she has to solve with her new partner, the easygoing and somewhat washed-up detective Karl Jäger, she is confronted with a brutal murder: psychiatrist Dr. Claudia Kretschmer is found dead.

Because detectives Jäger and Kraft botched an unauthorized operation, they now have to face the consequences: they are demoted and placed under the command of their colleague Hoffmann. In their private lives, too, things are not as they should be. While Jäger is kept busy at night by his young children, Lola and Andreas' relationship is in crisis. The Calw investigators are really not having an easy time of it at the moment. And then there's their new case, which seems to be a tough one. When businessman Till Ritter is found dead, everything seems clear at first: suicide. But the matter becomes more complicated. Why was Ritter's daughter kidnapped? And what is his son Philip hiding? And what does the body found in a nearby lake have to do with it? The three detectives and their new colleague still have a lot of work ahead of them, because there is still a long way to go before all the questions are answered and the case can be closed...

The wealthy car dealership owner Gerhard Binder has an accident with his car and is taken to hospital with serious injuries. Routine examinations reveal that this was an attempted murder. So detectives Jäger, Kraft, and Hoffmann must first investigate a case in which there are no deaths. But anyone familiar with Mania Pictures knows that this won't remain the case for long. The circle of suspects includes primarily Binder's young and attractive wife, as well as his broke brother, a washed-up porn producer. Suddenly, a mysterious stranger appears who obviously also has a bone to pick with Gerhard Binder. In a dramatic and lead-filled finale, the complicated case is finally solved and a big surprise awaits the police officers...
