In the murder case of the export and financial consultant Lessnik, the inspectors are puzzled. A lead leads to the former business partner of the murder victim. But exactly this said Karsten Holler was officially declared dead six years ago. During a motorcycle tour through the Sahara with Lessnik, Holler disappeared without a trace. Lessnik and Holler's wife Sarah were suspected of murder at the time. But for lack of evidence it had to beProcedure to be discontinued at that time. Now the question arises: Did Holler just fake his death back then? Ballauf and Schenk are apparently chasing an "undead". They don't know Holler's new identity or whereabouts. But via a tax CD from the Cologne tax office, they come across an interesting numbered account in Switzerland. Lessnik and Holler were involved in a dirty deal at the time.
