A shift in the Earth's axis triggers a series of strange events in the tranquil small town of Centerville. While Sheriff Cliff Robertson is still puzzled, his colleague Ronald Peterson is certain: it must be a zombie epidemic. These zombies, however, aren't just after the citizens of Centerville, but also the things they used to enjoy in life. They roam the streets, hungry for human flesh, coffee, and perhaps a glass of Chardonnay. When it turns out how to capture the undead ghouls, the police duo, armed with a machete and a shotgun and supported by their young colleague, begin hunting zombie heads to save the town from invasion. They receive unexpected help from the eccentric Scottish undertaker Zelda Winston, who wields her samurai sword with superhuman precision.
