The plot follows four friends who travel to Las Vegas for a bachelor party, only to wake up the next morning not remembering a thing and missing the groom, whose wedding is scheduled to occur the next day.
Basically the same plot as “Dude, Where’s My Car?” except with the added stress of the missing groom. Although, there’s no aliens in this movie, and the characters are mostly way less dumb. I enjoyed the movie (parts of it were hilarious), but I couldn’t help feeling at the end that most of it was superfluous, given where they eventually find the groom.
