Businessman Simons asks Dr. Franck for help after a fire in his not-yet-opened restaurant which caused the death of the cook. Simons suspects that it was either linked to racketeering or to the nearby innkeepers who already had to argue with him. Rainer asks Matula to investigate, but he's not really big on the idea because the nearby innkeeper Karin Winter is a close friend of him and her pub is his favorite one.
