They planned a Vegas bachelor party that they would never forget. Now they really need to remember what exactly went down! Whose baby is in the closet of their Caesars Palace suite? How did a tiger get in the bathroom? Why is one of them missing a tooth? And most of all, where is the groom?! What the guys did while partying can't compare to what they must do sober in an outrageous caper that has them piecing together all their bad decisions from the night before - one hazy clue at a time.

Two days before his wedding, Doug and his three friends drive to Las Vegas for a blow-out bachelor party they'll never forget. But, in fact, when the three groomsmen wake up the next morning, they can't remember a thing. For some reason, they find a tiger in the bathroom and a six-month-old baby in the closet of their suite at Caesars Palace. The one thing they can't find is Doug. With no clue as to what transpired and little time to spare, the trio must retrace their hazy steps and all their bad decisions in order to figure out where things went wrong and hopefully get Doug back to L.A. in time to walk down the aisle.
