To explore the unknown boundaries of suffering and to push the threshold of pain further still, three pitiless explorers of anguish abduct a helpless young woman. Intent on putting their youthful subject through the seemingly endless ordeal of their sadistic research, the men use increasingly brutal techniques to test the theoretical limits of human endurance. Then, the torturers continue the investigation with a heavy hammer, paving the way for the infernal pièce de résistance: a fine and shiny surgical needle. Has anyone survived the Devil's experiment?
