Ray Barone is a successful sportswriter living on Long Island with his wife Debra, daughter Ally, and twin sons, Geoffrey and Michael. That's the good news. The bad news? Ray's meddling parents, Frank and Marie, live directly across the street and embrace the motto "Su casa es mi casa," infiltrating their son's home to an extent unparalleled in television history.

Someone is killing off the female leads of the movie production "Bad Girls from Mars." The producers feel they should try to finish the film, even though they're making a lucrative amount from insurance payoffs, so they fly in European sex bomb Emanuelle as the new lead. Emanuelle immediately begins embarrassing the producers by leading a wild party life around town. Meanwhile the killings continue, and detectives try to stop the fiend responsible.
