Although the opening segment implies that Merlin's magical interventions in people's lives are intended to have a benign effect, in practice this proves to be far from the case.

The first story focuses on a married couple, Jonathan and Madeline Cooper. Jonathan is a respected, though obnoxious columnist, and Madeline is desperate for a baby, as she and Jonathan have been unable to conceive. The couple visit the store, where Jonathan berates Merlin and threatens to write a negative article in the newspaper that will cause his readers to avoid the store. Merlin loans Jonathan his spellbook as proof that he is actually the legendary wizard. Jonathan takes the book home and begins to toy with several of the spells. Jonathan becomes convinced of the book's authenticity when an unsuccessful spell to summon a spirit results in him having a vision of Satan and causing Jonathan to breathe fire. Jonathan quickly grows excited and becomes obsessed with the book's powers, but begins to dramatically age due to the rapid depletion of one's life force required to cast the spells. Jonathan attempts to transform his pet cat into a mystical servant, but it becomes demonic and proceeds to attack him. Using the spell from earlier, Jonathan breathes fire and burns the cat alive. By then, Jonathan has aged so severely that his hair is white and receded. Jonathan retrieves the book's rejuvenation spell and proceeds to create the required potion. He takes a sample of Madeline's blood and adds it to the mixture. Jonathan drinks the potion, but the spell backfires: Jonathan regresses into infancy. Madeline happily decides to raise her former husband as her own child.

In the second story, which bears a very close resemblance to Stephen King's short story "The Monkey", a thief steals a cymbal-banging monkey toy from Merlin's shop,^[2] and sells it to a novelty store, where it is quickly bought by a woman as a birthday present for her young son Michael. It soon appears that every time the monkey's cymbals are struck, a nearby living thing dies, including the family's pet goldfish and dog. Suspicious, the boy's father David consults a psychic friend, and she advises to throw the monkey away, which he does, but Michael finds it in the trash and returns it to the house. The monkey then attempts to cause the boy to be struck and killed by a passing car but he is saved when David manages to prevent the monkey's cymbals from coming together. Desperate, he takes the toy to a remote field to bury it, but a fierce storm and earthquake is summoned by the monkey in an attempt to stop him. David finishes burying the toy but is then injured by a falling tree, though his plan to be rid of the nightmarish object seems successful. Some time later, David's mother visits, bringing a present for her grandson Michael, which turns out to be the monkey, unharmed. The family attempts to flee as the monkey's cymbals go into motion, but before they can strike again, Merlin, who had been searching for the toy the entire time, suddenly appears and takes it back to his shop, promising to “deal with” the murderous object “later”.

The second segment of the film is a recut version of The Devil's Gift, a 1984 film made by the same director.^[3] Large elements of the original film's storyline are missing, and segments with Merlin are added to show him pursuing the toy monkey. The original film's dark ending, in which the monkey kills the entire family,^[4] is replaced with Merlin arriving just in time to stop it.

Mystery Science Theater 3000 version edit

The film was one of the last works to be featured on Mystery Science Theater 3000's original run (although its airing was delayed due to rights issues).^[5][6] The hosts and writers of the show used the sloppy editing on the second subplot, the disconnection between the two halves of the movie, and the wildly varying tone of the film as the basis for many of the jokes. The film's presentation as family friendly fantasy, juxtaposed against its dark narrative is also used as the basis of numerous jokes. The framing story of the Ernest Borgnine character telling these as stories to his grandson is also used for humor. A wraparound segment depicted host Mike (Michael J. Nelson) and his robot companions taking a look at an (invented) range of Ernest Borgnine children's books, whose benign titles and presentation belied the frightful nature of the stories therein, with the exception of one which has a macabre appearance but features an innocent story. Another host segment depicted Mike turning into a baby because of his disbelief in magic.

RiffTrax edit
