Movie star Lilly (Bette Midler) and journalist Dan (Dennis Farina) have been happily divorced for 12 years. Everyone, especially their daughter Molly (Paula Marshall), would like it to stay that way. But when Molly's boyfriend Keith (Jamie Denton) proposes marriage and insists on a large traditional family wedding, nothing short of a natural disaster is going to keep Molly's parents from coming. Even though they swear to behave, everyone braces themselves for the inevitable- after all, Lilly and Dan hate each other with nuclear capacity.
