A sitter's last-minute cancellation leaves Samantha to watch Jonathan while Angela and Tony go to a parents' meeting at school. Samantha panics when Jonathan inadvertently tosses a piece of jewelry down the sink drain. Although Tony had told her not to have any guests, the house is soon full of her friends: Chad, a boy who thinks he can retrieve the missing jewelry, and four of Samantha's friends who come to admire Chad. Tony and Angela return home just as the kids are sneaking out.
