Praying Mantises have evolved into the dominant species on Earth, having wiped out humans years ago after a genetic experiment evolved the species into man-sized, super intelligent insects. But they don't just roam the planet aimlessly. The Mantises have taken over our jobs. Kept the generators running, the oil pumping, and the economy in place. They're people, just like us ...Except that they're cannibalistic, blood thirsty nymphomaniacs who love biting the heads off their partners while they mate. Matthew is a high school history teacher. He does his best to educate the young mantises and tame the savage side of their nature, until the day he comes home to find his wife ready to mate. Anyone who knows anything about Mantises knows that mating is a death sentence for males of the species. But when Matthew's wife partially decapitates him during sex, he crawls out to the woodshed to die, only to find an old haunted chainsaw, possessed by the spirit of his home's dead human owner, who just happens to be an occult sorcerer and serial killer known as The Growler's Phantom. Now resurrected, Matthew vows revenge on his murderous wife, and her new husband Nicko as well as anyone else who gets in his path. Part Texas Chainsaw Massacre, part Evil Dead, pray this mantis doesn't find you next!
