In England, Professor Harrington (Maurice Denham) begs his rival, Dr. Julian Karswell (Niall MacGinnis), to rescind the curse he inflicted on Harrington; in return, Harrington will cease his investigation into Karswell's Satanism cult. After learning that a parchment he gave Harrington has been destroyed, Karswell ushers him out and promises to do what he can. As Harrington arrives home, he perceives a gigantic demon materializing in the trees. Harrington tries to escape in his car but crashes into powerlines. The authorities declare electrocution as the cause of death.
