Offspring

Something deadly has returned to the woods and seaside cliffs of Dead River, Maine. An evil flesh-eating clan, thought to have been exterminated ten years earlier has returned with an insatiable appetite. David and Amy Halbards family and their house guests are about to come face-to-face with a blood-thirsty pack of wild children led by Woman, the last survivor of a primitive, cave dwelling tribe of predatory savages. The only one who can possibly save them and put an end to their reign of terror is retired sheriff George Peters. From the producers of The Girl Next Door and Headspace, and written by renowned horror-writer, Jack Ketchum - Offspring is a "nerve-jangling, gut-wrenching thriller of which Ketchum should be proud."
