Robert Altman's over-frenetic satire on American marriage rituals and hypocrisy concerns the upper-crust marriage between Dino Corelli (Desi Arnaz Jr.) and Muffin Brenner (Amy Stryker). As the film begins, a senile bishop forgets the lines to the wedding ceremony and Nettie Sloan (the groom's grandmother) drops dead in an upstairs bedroom. Nettie's death is not disclosed to the two families who converge at the wedding reception. As the two sets of in-laws slam into each other, the bride and groom disappear in the ensuing whirlwind of chaos as both extended families vie for sexual favors and try to keep hidden never-discussed family secrets. Regina Corelli (Nina Van Pallandt) is revealed to be a drug addict, while Luigi, is endeavoring unsuccessfully to keep his Mafia connections under wraps. Meanwhile, the bride's family, although more down to earth, are revealed to be no better. Tulip Brenner (Carol Burnett) begins to flirt with one of the wedding guests, Mackenzie Goddard (Pat McCormick), while Snooks Brenner (Paul Dooley) acts like a lout and drinks heavily. And flying around the edges of the action like Tinkerbell is Buffy Brenner, the Brenners' youngest daughter, who is pregnant by the groom. As other characters bang into each other -- sexual degenerates, hard-nosed radicals, raw-boned emotional wrecks -- the wedding reception heads for its inevitable nuclear explosion.
