Trevor is `between jobs`. He spends his days avoiding his nagging heifer of a wife by hiding out in his allotment shed and painting figurines for his wargames with his agoraphobic friend, Graham, and dreaming of his heroic alter-ego, the battle mage Casimir the Destroyer. When Mr Parsons, one of the other allotment tenants, petitions to have Trevor removed from his disgrace of a plot (he`s not there to grow stuff!) an argument ensues that leaves Trevor with a corpse to hide. Unfortunately, this untimely accident coincides with the zombie apocalypse and Mr Parsons` return is just the beginnings of Trevor`s problems. More pressing is whether or not he should try and save his wife and her beautiful best friend, who both he and Graham have a thing for.
