William Brown, a neurotic, self-absorbed musician decided to complete his prog-rock magnum opus, faces a artistic roadblock within the type of a loud and grotesque neighbor named Vlad. Lastly working up the nerve to demand that Vlad hold it down, William inadvertently decapitates him. However, whereas trying to cowl up one homicide, William’s unintended reign of terror causes victims to pile up and turn out to be undead corpses who torment and create extra bloody detours on his street to prog-rock Valhalla.
