Welcome to Drunk Zombies.
Its 2018 and a new virus is spreading called the "Vodka Virus". People who become infected with this virus slowly start to decay away until they die. The only thing that slows down the virus is alcohol. Which has caused mass panic and has created a worldwide shortage of alcohol.
Jonny, the owner of "Jonny's Pub", is trying to protect himself and his friends from acquiring the virus. Along with trying to protect his precious stash of booze.
