Dr. Josef Stein was trained as a man of science and rationality, but after a tragic experience, he believes that there is something withing--or even without--the human body science cannot explain. And Stein would do anything to witness it! When his patients begin seeing a ghost, and a woman suspected of killing her child even accuses this spirit of the crime, Stein takes it upon himself to investigate. Unexpectedly, evidence of a supernatural phenomenon starts to mount. The good doctor's quest to see is ignited with fervor. He thinks is on the verge of uncovering the veracity of a thousand year old myth when his research gets interrupted by the Gestapo. Stein turns to his colleagues and friends for help, but they begin to suspect that the doctor's determination may have unhinged his mind. Has Stein, after years of treating the crazy, gone mad himself?
