In 1968, humanity started cloning its first living creatures...sheep. They codenamed the project Dolly. Everything was going well, until there was a malfunction in one of the computers. The sheep were cloning too fast! By the time the scientists noticed, it was too late. These freaks quickly invaded nearby towns and farms and then spread over most of the world. And then an unexpected hero arose from the darkness. Joe and his trusty shotgun Hank.
