New Hollywood Movie Plot

Picture this: A man in a house. The house contains two stories with a microwave in the eastern first floor side. This is a nice microwave. It is very efficient and works nicely. But picture this this man has a disease. He is obsessed with slaying zombies. Killing them in an apocalyptic world. The problem though it is actually the year 2010 so there are no actual zombies. Yet he thinks everyone is a zombie and proceeds to act like it. Stealing and killing everything. That is pretty much the movie.
