The body of an elderly restaurant owner is found hanging at the Blue Wonder. The corpse of the old man, wrapped in an archaic priest's robe, bears strange burn marks. Was the deceased a war criminal in hiding, murdered out of revenge after seventy years? The investigation leads the homicide squad to a Viennese journalist who had stumbled upon an unimaginable crime from the Nazi era just before she disappeared in Dresden. While Commissioner Conny Clausius cuts her vacation short with Raik Winter to eagerly tackle the new case, the attractive judge Marijana Kettler, who worked for the murder victim, receives unexpected help and makes an incredible discovery in the restaurant's basement.
