What if we lose control of who we are? In this terrifying, contemporary new version of Robert Louis Stevenson's renowned tale of good and evil, two medical students, Jay and Mary, take their desire to be different to a frightening new level. They begin experimenting with a strange drug similar to ecstasy, and their personalities quickly start to unravel in ways they can't control. Even though tragedy unexpectedly strikes, Jay keeps altering the drug, unaware of how it is taking over every aspect of his life and the essence of who he is. His terrifying descent is chronicled in bizarre video diaries that ultimately reveal to everyone the maddening game they dared to play.
