They seek shelter in a garish, loud apr�s-ski tavern that is hosting an all-night party for the last night of the season. Things go from bad to worse when a scientific experiment conducted by a local entrepreneur unleashes an epidemic of zombies and mutant wildlife, but this is mostly lost on the local drunkards as they themselves are not always so easy to distinguish from zombies. Steve, Branka and Josh have to find a way to survive this hellish night. Finally, their epic battle for survival leads to them having to use their snowboarding skills to defeat the raging apr�s-ski zombies once and for all.
