 More than 300 years ago, 3 witches were sentenced to die in Salem, Massachusetts and a boy was turned into a cat (a black cat, naturally). Now it s Halloween, and the witches (who fly on [I kid you not] vacuum cleaners) are back. This time, they ve got their eyes on immortal life and have turned their wrath on trick-or-treaters and it s up to the 300-year-old cat to save the day.
