On the eve of his wedding to his longtime girlfriend, Debbie (Tawny Kitaen), unassuming nice guy Rick (Tom Hanks) is dragged out for a night of debauchery by his friends. The gang includes cocky Jay (Adrian Zmed), self-appointed ringleader of the party, and depressed, recently divorced Brad (Bradford Bancroft). Along the way, they run into Debbie's wealthy, disapproving father (George Grizzard) and her ex-boyfriend, Cole (Robert Prescott), who attempt to stop the wedding in an unexpected way.
