Zombie Killers: Elephant Graveyard (DVD)

The rural town of Elwood has always been a "bubble" against the backdrop of a suspected global virus where infected humans don't die, instead they roam around trying to spread the sickness in a grisly, horrific way. The Zombie Killers, a small band of young adults trained by ex-military soldier Seiler (Billy Zane), have sworn to protect the town and aim for the head if anyone threatens Elwood's last survivors.
