17 year old high school outcast Josh searching for his missing girlfriend Sam in post-apocalyptic Glendale, California. He is joined by a ragtag group of misfits including a pyromaniac 12 year old, Angelica, and Josh's former high school bully, Wesley, now turned pacifist samurai. Josh and the group tries to stay alive amidst the horde of Mad Max-style gangs (evil jocks, cheerleaders turned Amazon warriors), zombie-like creatures called Ghoulies, and everything else this brave new world throws at him.
