Peter and Lisbeth are two young but unfortunate lovers living in a rigid rural community in the Black Forest. She comes from a wealthy family of glassblowers; he is a poor coal worker on the lower end of society. To become rich and respected Peter makes a pact with a devil named Dutch Michael who rips out his heart and replaces it with a stone. Robbed of all warmth and feeling Peter becomes a cold-hearted go-getter who rapidly achieves his goals. Ruthlessly he strives for money and power. But Lisbeth no longer recognizes Peter as the man she once loved and turns against him. There is only one way for him to put things straight: Peter must get his heart back.
