A nice weekend away for the Rhoades' and the Bundys turns into misery when Peg, Kelly and Marcy all have their period at the same time, torturing the men.
The Bundys are a stereotypical 'white trash' American family. Al is a shoe salesman who is fond of frequently reliving his doubtful 15 seconds of fame on the football field. Al is terrified of the all-to-frequent amorous advances his ditsy wife Peggy, a woman who must spend most of Al's wages at the salon and the mall. They have two children: Kelly, the stunning but superficial party animal, and Bud, who is too wrapped up in himself to realize his goal of 'scoring' with a girl.
