In her old, diseased age Aunt Gail, who learned a trick or two from grandmother, and two lady-friends sell their souls, magically resurrecting the demon Kryto, in exchange for the benefit of his unique power to grant mortals health, beauty and even youth. But fearing to be vanquished again by three witches, he first demands magical powers, which Gail cunningly steals for him from the sisters, abusing their own Book of Shadows, then destroys the two other rejuvenated witches and keeps threatening Gail into luring other mortals, thus enforcing a magical fight to the death with the Charmed ones, whose only advantage is the knowledge of the finer points of using his freshly stolen powers...
