Straight-laced Jordan (Martin) is about to marry her perfect match, clean-cut ambitious attorney Peter (Snedeker). Before she heads down the aisle, she and her best friends Claire (Adrienne Frantz) and Jessica (Daphnee Duplaix) head to Vegas for a bachelorette party. Determined to get Jordan to loosen up, Claire steers the girls to the hottest nightclub for a few drinks and some fun, because what happens in Vegas stays in Vegas, right? But when Jordan wakes up the next morning unable to recall the night before, she panics when she finds herself in movie star Matt's (Ethan Erickson) hotel suite with a gigantic diamond on her finger and a marriage certificate lying nearby. Before she can have the marriage annulled and put this nightmare behind her, the impromptu wedding explodes into a publicity stunt fueled by Matt's manager Eric (Bruce Nozick) to promote his latest movie. With her wedding day approaching, Jordan becomes more confused than ever when she starts to fall in love with the movie star she's married to instead of the fiancé she thought was her perfect match.
