In a post-apocalyptic future, Medina has become the last bastion of a humanity fighting the nightmarish and infectious creatures known as the Drax. The shield that protects the city won't hold out much longer, and humankind appears to be condemned. The only ray of hope is a "package" ripped from the Drax by the soldier, Karloff. This package is in fact 14-year-old Hadron, said to carry within her the Great Redemption. But will the humans manage to control this young girl's force?
