When it comes to raucous, raunchy and riotously inappropriate pre-wedding behavior, why should guys have all the fun? Control freak Reagan (Kristen Dunst), smart-mouthed Gena (Lizzy Caplan) and bubble-headed Katie (Isla Fisher) celebrate the impending nuptials of their longtime, high school whipping girl Becky (Rebel Wilson) in an epic girls' night out filled with strip clubs, ex-boyfriends and innumerable unmentionables (among them, Becky's wedding dress). It's the ultimate chick flick comedy for everyone to love, honor and cherish forever.
