from wikipedia:
Jessie Montgomery (Ally Sheedy) is a spoiled rich girl in her mid-20s whose hard partying lifestyle and lack of self-respect as well as a lack of respect for others is starting to wear thin on her single father Charles (Tom Skerritt), a wealthy philanthropist, and on her boyfriend Brent (Jason Beghe), who breaks up with her after finally getting frustrated with her immature and self-destructive behavior. When Jessie is arrested for drunk driving and drug possession, she finally pushes Charles beyond his limits. He blames himself, as many years ago his wife died of cancer at a time when Jessie was a small child. Feeling it would help her cope with the death of her mother, Charles seldom laid down the law, often spoiling Jessie. While in the company of family retainer Woodrow (Theodore Wilson), he says the one thing he thought he would never say... he wishes he had never had a daughter. In pops Stella Winston (Beverly D'Angelo), a fairy godmother who has been assigned to the Montgomery family. To keep Jessie from ruining her life, Stella casts a spell "erasing" Jessie's life as it is, as if Charles did never have a daughter. Then she bails Jessie out of jail.

When Jessie tries to go home, her father doesn't recognize her and claims that he has no daughter. Stella appears and tells her that she's getting what she deserves. She tells Jessie that if she wants to eat and have a place to sleep, she will have to find employment. A college dropout who has never worked a day in her life, Jessie is forced to find work as a live-in maid for an eccentric couple named Starkey (Valerie Perrine and **** Shawn) who got rich by winning the lottery some years back who are trying to make it in the music industry as talent agents.

Jessie has to interact with the other mansion staff, consisting of former singer-turned-cook Audrey (Merry Clayton), Hispanic servant Maria (Begoña Plaza), and chauffeur Nick (Michael Ontkean), a struggling songwriter. Jessie learns the true meaning of love, friendship, hard work and self-respect. When she chooses the happiness of her new friends over her own, she is rewarded with having her old life returned to her, and being reunited with her father. However, her attitude is now much improved.

This should be on Rifftrax because...
it's one of Dick Shawn's last performances
Roger Ebert of the Chicago Sun-Times "found it too easy to anticipate most of the big moments and too hard to believe that Sheedy was really a spoiled, mean-spirited rich bitch."

Ally Sheedy in a maid uniform is hysterical!
