When George and Marsha take a vacation to Florida they leave Mr. Belvedere in charge of Kevin, a grounded Heather and Wesley. Immediatly after they leave, all hell breaks loose, when Heather sneaks out with her friends to see a Prince concert and Wesley brings a massage therapist over for a stressed out Belvedere.
George takes Mr. Belvedere and Wesley to a wrestling match where a spectator Max 'Meat Grinder' Maxwell (Hard Boiled Haggerty) picks a fight with George, which ends with Mr. Belvedere defending George. Dealing with a bruised ego, George becomes impotent and wanting to feel like a man, he buys a motorcycle. Meanwhile, taking a cue from Mr. Belvedere, Wesley begins to get in fights at school.
The ad that Marsha has placed seeking a housekeeper is answered by Mr. Belvedere who finds himself needing to adjust to suburban life as well as the Owens needing to adjust to having Mr. Belvedere around. Meanwhile, Wesley's hamster has gotten loose somewhere in the house, Heather's boyfriend is pressuring her into a more serious relationship and Kevin brings home a bad report card.
