Three hundred years ago, the witch Mad Dolly is captured on the orders of Lord Garrick. She is about to be burned at the stake when she invokes the Devil, causing the executioner to catch fire. Garrick rushes back to his house, where a disembodied arm punches through a wall and strangles him. His wife is then confronted by a sword-wielding Mad Dolly, who beheads her and curses the family's descendants.
