Four young women comfort themselves with an Acapella version of 4 Non Blondes' 'What's Up' while hiding from the cops in a dumpster during one wild Bachelorette party that has flown off the rails. Of course, a scary surprise awaits them as they reach their crescendo in our exclusive clip from Best Night Ever, in theaters this weekend. Watch and learn why the trash bin behind a strip club might not be the best place for a game of hide and seek.

Bride-to-be Claire, her sister Leslie, fun-loving Zoe, and quirky new friend Janet set off to Las Vegas for a one-night Bachelorette party that turns out to be more than they bargained for. A series of unexpected adventures, including getting kicked out of a strip club, being mugged, and getting pummeled by the Las Vegas reigning gelatin-wrestling champion, Veronica, rips them from the glitz and glamour of the Las Vegas strip and places them smack dab in Vegas's seedy underbelly. Determined to keep their Bachelorette party dreams alive, the girls' band together and embark on the wildest night in Bachelorette party history. Fueled by sex and booze, this raunchy, riotously hilarious, out-of-control blowout is, for better or worse, all caught on tape. And is destined to go down as the Best Night Ever.
