A female college student is kidnapped and held captive in an abandoned factory. Three to four men record her on video and in photographs, documenting her physical and psychological deterioration. They subject her to relentless abuse, including sneaky, sadistic acts while she is unconscious, merciless rape upon regaining consciousness, and violent assaults when she attempts to escape. She is tortured with water in the rain, and ultimately suspended and brutally punched with a fist in an extreme, merciless attack.
