Christl Bachmayr was killed in her ceramics shop with a floor vase, the receipts from the cash register are missing. First, her employee Ludwig Reichl is suspected. He had helped himself at the cash register and should therefore be terminated without notice. But also a competitor of the victim Franziska Köhler comes into the focus of the inspectors Stadler and Hansen. The two used to run a ceramics shop together. In the dispute, they ended their business relationship, and Franziska Köhler finally took Christl Bachmayr to court for copyright infringement. When blood is found on a shard of the murder weapon and analyzed, it is clear that it must be a male perpetrator. Will the victim's recovered laptop put the detectives on the right track? While Hansen and Stadler are investigating, there is excitement in the police station: has Commissioner Stadler actually registered on a dating portal? Marie Hofer and Miriam Stockl devise a plan to find out whether Stadler is actually cheating on his wife Hilde on the internet.
