When a bachelor party and a bachelorette party cross paths in Vegas, only the best man and the maid of honor can save their friends from a night of epic "mistakes."

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, rip them from the glitz and glamour of the Las Vegas strip and places them smack dab in Vegas’ seedy underbelly.

Fueled by sex and booze, this raunchy, riotously hilarious, out-of-control, blow-out is, for better or worse, all caught on tape. And is destined to go down as the Best Night Ever.
