Vile (DVD)

Fifty years ago Yale University professor Stanley Milgram held a series of social experiments based on Nazi war criminals' psychology. They were devised to answer a simple question: how far are people willing to go when instructed by authority? Nick, his girlfriend Tayler and their two best friends are about to find out... Abducted after a camping trip, they wake up in an unknown prison with two vials wired into the base of their skulls. They are not alone: another four people are in the same nightmarish predicament. Their task, set by a mysterious video figure, is to fill the vials with chemicals that the human body only creates when it senses pain. A lot of pain.
