Being a teenage girl in the valley is never easy. Peer pressure, social awkwardness, alienation, boyfriend trouble, ignorant parents and the apocalypse. Yes, the apocalypse. When squabbling teenage sisters Reggie and Sam wake up one morning to find the human race has been thrown into extinction, they decide to track down a radio signal and hopefully other survivors. It's a journey fraught with flesh eating zombies, demented scientists and 1980s teenage girls brandishing machine guns. Who the hell said Armageddon couldn't be fun?
