The subcontractors have stopped work on a large construction site in Leipzig and reported the building contractor Peter Ludwig to financial fraud. A surprise acquittal outraged those in the courtroom. The next day, the chief inspectors Ehrlicher and Kain are called to Ludwig's villa. The real estate investor was shot dead in his house and several valuable works of art were stolen. The first suspicion falls on the cleaning lady Marion Höfner, who found the dead man. The inspectors find out that she recently gave her husband Jürgen access to the house. However, the unemployed craftsman has an alibi for the time of the crime. Ehrlicher and Kain then interviewed Ludwig's young, ambitious lawyer Corinna Becker.
She tells them that her client is still in the courthouse by Werner Mühl, the manager of one ofLudwig, who was forced into bankruptcy, was attacked with a paint bag. When the inspectors then find some of the stolen art objects at Mühl's home, they seem to have reached the goal of their investigation. Mühl admits the burglary, but denies that Ludwig was murdered. He also blames the credit institutions that work with fraudsters like Ludwig for his financial hardship. dr Stefan Bischof, however, assured the inspectors that his bank handled the loan granted to Ludwig seriously and had nothing to do with the allegations of embezzlement. But when they check Ludwig's business accounts, the inspectors find out that over several million euros have disappeared.
Ehrlicher and Kain solve a case where the interests of creditors, lenders and the judiciary intersect.
