Heart of Stone (2014)

Penniless Peter Munk toils day after day as a charcoal burner in the Black Forest. In order to finally achieve the wealth he longs for and thus get closer to his previously unattainable crush Lisbeth, he turns to two mysterious forest spirits with his wishes. While the cranky little glass man can't really help him, the sinister Dutchman-Michel promises him an end to his financial worries. However, he demands Peter's heart in return and puts a cold stone in his chest instead. Although he can now afford everything and finally take Lisbeth as his wife, Peter no longer has any compassion, which soon has devastating consequences not only for himself but also for his fellow human beings.
