At the end of the nineteenth century, the rich have great interest in the occult; tables dance everywhere, and ghosts speak in many a darkened room.
Willem Wolf, a wealthy young man, has a passion for exploring psychic phenomena and exposing the charlatans. He believes many are fraudulent and he becomes a one-man inquisition hunting for the truth, first giving the psychics the benefit of the doubt until he sees through their trickery.
Then he decides to find out what happens when more than a dozen mediums concentrate on the same thing at the same time. He finds himself in a mesmerizing world where the intriguing story of the long-lost Nibelung Gold seems to be a fact.
Wolf begins a journey he never expected, dealing with dishonest and evil people while searching for the truth of the legendary Nibelung treasure or Rhine Gold that has been lost since the 5th century along Germany's Rhine River.
