Brilliant British teen Graham (Hugh O'Conor) comes from a dysfunctional family and lacks any sense of right and wrong. A whiz at science, he's mesmerized by poisonous concoctions and murder. After Graham poisons friends, family and co-workers, he's caught and sentenced to a psychiatric institution, and then bamboozles his shrink into thinking he's cured. Benjamin Ross directs this darkly comic tale based on a true story.
