Let me start by saying that this movie is insane. Beverly DeAngelo is released from jail and becomes the nanny for two precious children who's parents are dubbed "the worst ever." She then gets the idea that she could sell the kids to make a quick buck. Let's just say there's a dead monkey, an obsessive compulsive yuppy couple, and Beverly DeAngelo learns a lesson.

Just wanted to add an apology: I posted this in the main section instead of posting here, and I apologize for not posting a recommendation in a spot that says, very boldly, BAD MOVIE RECOMMENDATIONS.
