After a night of debauchery, five military buddies wake up in the drunk tank only to find out that while they were passed out in their cell, the zombie apocalypse kicked off. Armed only with billy clubs and their military experience, they break out of prison and fight their way to their old base. Along the way, they pick up a whole lot of weapons, a couple of damsels in distress, and accidentally, the cure. They woke up that morning fighting hangovers. Now the fate of the world hangs over their ability to fight.
