Amy and Sophie, two young American foreign aid workers, are trekking through the enigmatic Caucasus Mountains. They become disoriented and stumble upon a location that does not appear on any map and is completely isolated from the rest of the world. There were no telephones or roads, only the dark, foreboding mountains. In this archaic world, one man strikes fear into the hearts of all. The Breeder abducts young sin-tainted women, such as Sophie. Provoked by her naked swim in a lake, he violently abducts Sophie and transports her to his breeding station, a secret former Soviet laboratory.
