Harrison Williams needs a wife to gain access to his trust fund account. He goes to Las Vegas to meet someone, but there's a mix up and he ends up at the Chapel-O-Love exchanging vows with Penny, a spirited girl in a cheap veil. When they realize the mistake, he convinces her to go back to Bel Air with him to prove that he's married, and he agrees to pretend to be William so her family doesn't have to know about her big mistake. Sounds like a good plan. What could go wrong?
