Peeping Tom has spent years locked up in a mental institution because of his penchant for lifting girl's skirts. So when a busload of Catholic schoolgirls arrives on the scene, he thinks all his Christmases have come at once. But these aren't normal schoolgirls. They're here to chew gum and kick ass, and they're all out of gum.

Join Tom and his fellow psychiatric inmates as they fight to survive the zombie apocalypse, nuclear annihilation, and the perils of a diet consisting only of rice and beans.

Will the pervert prevail? And if not, how many skirts can he lift before he gets his comeuppance? Will Alice the teenage vampire indulge in her own version of the Holy Communion? And most importantly of all...Rebecca, will you stop pulling Jasmine's hair! This is your last warning!
