Mörderischer Besuch plot
Felix von Gelden (Joost Siedoff), the father of the attractive Nita von Gelden (Liane Forestieri), has been stabbed and Chief Inspector Michael Ochjaon (Heiner Lauterbach) investigates the case. The case looks like a robbery murder, because a valuable painting has been stolen. Earlier in the evening, the old man had a visit from Nita and her two brothers Theo (Benjamin Sadler) and Gabriel (Wilfried Hochholdinger). When it becomes clear that the visit ended in an argument over an unknown work by Vivaldi, which once saved Felix's life in the concentration camps, the case takes an unexpected turn.
