 Offbeat fashion student Betsy Hopper and her straight-laced investment-banker fiancé, Dylan Walsh, just want an intimate little wedding reception, but Betsy s father, Eddie, a Long Island construction contractor, feels so threatened by Jake s rich WASP parents that he blows the ceremony up into a bank-breaking showpiece, sending his wife, Lola, into a financial panic. Pressure from Betsy s extended family to include their joint Jewish and Italian-Catholic heritage in the ceremony doesn t do much to assuage the title character s worries, nor does the lovelorn bitterness of her older sister, Connie, who s single, her parents assume, because she has the audacity to pursue the unfeminine profession of police officer. With all of his funds tied up into the money pit of a house he s building, Betsy s dad has to turn to his crooked brother-in-law, Oscar, for financial assistance, and soon a soft-spoken but menacing young mobster named Stevie Dee is supervising Eddie s construction project and casting his romantic aspirations toward the clueless Connie.
