The black forest in the 19th century. A magic place with ghosts, good and bad, living in it. Peter Munk is a poor but goodhearted young man, desperately wishing to be rich. Tempted by the evil ghost of the woods, he trades his warm heart for a heart of stone. He becomes rich but turns into a merciless and cruel man. Is there still hope for him?!
Unfortunately the movie The Cold Heart is not yet available on HBO Max.
