Conny Mey (Nina Kunzendorf) and Frank Steier (Joachim Król) are called to a crime scene in downtown Frankfurt. The dead is the prostitute Ramona Förster. Police colleague Seidel (Peter Kurth) also appears at the scene of the crime and is given a new chance to support Conny Mey and Frank Steier. Seidel learns from the shady reporter Kurt Eggers (Martin Kiefer) that a very similar case happened six months earlier in Offenbach. It could be a serial killer. Steier warns Conny to deal with the murders . He is afraid that Conny will become too emotionally involved in the case. Meanwhile, however, she is already on the trail of Ramona Förster's ex-husband, who was with her at the time of the crime.
Everything points to him as the culprit, there is another murder of a prostitute, but Markus Förster (Uwe Bohm) seems to have an alibi. While Steier is busy analyzing the case in the police station, a race against time begins for Conny Mey, which is increasingly tugging on her nerves and her self-image as a police officer.
