The Master Physician [Doktor. X]

Goethe’s Faust myth makes an appearance in this drama about a dispute between two scientists. When Doctor Voluntas discovers that his rival, the virtuous Doctor Felix, is about to overtake him in the preparation of a serum for cancer, he decides to lure the good doctor into corruption. An innocent woman, Margaret, is reeled in as a decoy and it works! Doctor Felix soon forgets both about his work and himself, while the devil stands ready to take possession of his soul. (Stumfilm.dk)
