The young head of department Armin Lohmann is found dead in his apartment. The first suspicion falls on his wife Katrin. The chief inspectors Saalfeld and Keppler find bloody footprints at the scene of the crime, which indicate the presence of a strange woman on the night of the crime. Did Katrin kill her husband out of jealousy? Was the unknown witness to this murder? Or was she the culprit herself? The Leipzig building contractor Stefan Rose, with whom Lohmann met the evening before, would also have had a motive – because the head of the office put his company under pressure by stopping construction. Did Rose Lohmann want to speed up the political end? Or was he trying to hit him with abribing prostitutes? This suspicion arises when the body of the young Czech Alena Buranek, who died as a result of mistreatment, is found a short time later.
Officially, she was employed as a temporary worker by the "Rapid" temporary employment agency and worked as a chambermaid in the "Hotel Elster". Ulrike Horn, owner of the company, claims to have known nothing about Alena's "sideline" as a prostitute. The inspectors Eva Saalfeld and Andreas Keppler are confronted with the excesses of the modern labor market: Temporary work and illegal employment seem to encourage people to be abused.
