In a tradition as old as Vegas itself, four friends head off for the buck's night of one of their number. There is drinking.... lots of drinking. And the next morning, in the debris of a ruined hotel room, three of the friends wake up to discover the groom-to-be has gone missing, and none of them can remember what's happened for the last 12 hours.

If nudity (female AND male), crude language, violence, drug use or the sight of blood offend you, this might be the night for you to stay home and do a little bible study instead (I recommend Corinthians). If it seems right up your alley, then you're in for a treat - this is crude hilarity done right, as two reasonably average guys (and Galifanakis' Alan, who is, um, a little 'different') suffer the ultimate morning-after-the-night-before.
