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.
