The Devil's Assistant is a silent drama film directed by Harry A. Pollard and starring his wife Margarita Fischer.
Doctor Lorenz (Monroe Salisbury) is in love with Marta (Margarita Fischer), but she spurns him and marries John Lane (Jack Mower), leaving him bitter and resentful.
Aided by Marion (Kathleen Kirkham), a friend who is in love with John, Dr. Lorenz drives Marta to addiction and dependence on him and convinces her to leave her husband.
In a red-tinted film sequence, Marta sees herself transported to Hades, with hellish visions of torture in “The Devil’s Crucible,” including skeletons on horseback, three-headed dogs, and winged demons with pitchforks.
