On the night before an old friend's wedding, three frisky bridesmaids go in search of a little fun but find much more than they bargained for. With lovely Becky set to marry her handsome sweetheart, Dale, the remaining members of her high school clique reunite for one last bachelorette bacchanal in the Big Apple. Regan is an overachieving, uber-Maid of Honor who's secretly smarting over the fact that she's not the first to marry, while Gena is a whip-smart cynic who's actually a closet romantic, and Katie is a ditzy beauty who loves the good life. But when Becky insists on keeping the bachelorette party tame, the women proceed with an after-hours celebration of their own.
