Joe, who works at his dad's plumbing store, meets Valerie at a disco and a romance begins. But Joe's roommates, hearse driver Paulie and chauvinist Frankie interfer as does Valerie's divorced mother Stella with whom she lives.
The newly-married Joe and Valerie take a flashback look at the hilarious events that occurred before their wedding: Frank and Paulie feuding over who will be the best man and Stella threatening to boycott the wedding if her ex-husband (Valerie's father) shows up.
