Let's Go Play at the Addams'

Barbara is an ordinary twenty-year-old student who is hired to look after two children of a wealthy family, the Addamses, while their father and mother go on vacation for a week. She has a large secluded house, a car, and Cindy and Bobby, the children she is watching over, are obedient and kind. But only at first glance. One morning, Barbara wakes up tied to the bed. At first, she thinks the kids are playing a joke or, as they explain, they want to feel free from adult supervision. But the joke drags on and soon turns into a real nightmare. After all, Bobby and Cindy have friends, and they have completely different plans.
