Sir Edward Markham is the victim of a voodoo curse which has caused his
face to become horribly disfigured. He is kept captive in the attic of
his house by his brother Julian. Sir Edward escapes, moves in with an
unscrupulous doctor who hires grave robbers to steal bodies for his
research, wears a red hood over his face, and kills a good number of
townspeople before the surprise ending.
