Prisoners who want to be released as soon as possible naturally choose to take the test, not knowing what kind of test it is.The test, however, was just a way for the sadistic female guard to pass the time and satisfy her own sexual desires, a trap to humiliate and masochize the prisoners by treating them like toys. The prisoners continue to endure the rigorous tests of the female guard, believing that they will be released soon, but what is the end result?
