Zombieland is the story of a virus that has hit the world turning everyone who is infected into flesh eating members of the walking dead. The movie follows Columbus, a scrawny neurotic twenty something year old who is the last person you would expect to survive something like this. However, it is actually his obsessive compulsiveness and paranoia that is the very thing that allows him to survive this horror by creating a list of rules to keep alive. Along the way he meets up with Tallahassee, a man who perfected the art of zombie killing, as well as Wichita and Little Rock, two sisters whose goal in life is to make it to Pacific Playland, a giant amusement park on the west coast. Only one of these characters reveal their real name because they believe it will keep them from getting attached (Wichita says her name is "Krista" towards the end of the film).
