Three groomsmen find themselves in a quandry when a trip to Las Vegas goes all wrong. The guys seem to have no recollection of what transpired the night before and their soon-to-be-married friend is missing. Moreover, when they wake up from their night of revelry they find themselves with a tiger, a chicken and a six-month old baby. Worst still, the wedding takes place in LA and they have only hours to find the groom and take him back before the ceremony begins.
