“The Bregenz Plague penny is no legend” yells an elated scuba diver when pulling up a treasure of old coins from Lake Constance. Shortly later, he is found dead sitting on a bench on the shore, his mouth sewn up, a coin is inside his mouth.
For detective Hannah Zeiler (Nora Waldstätten) and her colleague Micha Oberländer (Matthias Koeberlin) it is obvious that the perpetrator must have known the Bregenz folklore: Gold coins were minted by the church to appease witches and to head off the Plague.
Is this indeed a “curse from the depth” or is someone’s diabolical murder plans?
