Uptight Jordan (Martin) is on the verge of marrying Peter (Snedeker), a driven and polished lawyer. Before tying the knot, Jordan and her closest friends, Claire (Adrienne Frantz) and Jessica (Daphnee Duplaix), take off to Las Vegas for a bachelorette bash, because, as the saying goes, what happens in Vegas stays in Vegas. However, Jordan wakes up the next day with no memory of the previous night and is shocked to find herself in the hotel suite of movie star Matt (Ethan Erickson), sporting a massive diamond ring and a marriage certificate nearby. Just as Jordan plans to annul the marriage and move past the ordeal, the spontaneous wedding becomes a media sensation, orchestrated by Matt’s manager Eric (Bruce Nozick) to boost his latest film. As her wedding day looms, Jordan is more bewildered than ever, as she finds herself developing feelings for the movie star she accidentally married, rather than the fiancé she once believed was her ideal partner.
