Lewis Sezon 5 Odcinek 3: The Mind Has Mountains

Detective drama. Student Amy Katz volunteers for a clinical trial being held at one of the colleges to test a new ketamine-based antidepressant drug but things go tragically wrong and, when she is found dead, Lewis and Hathaway are called in to investigate. The pair struggle to discover whether Amy's death is a direct result of the experiment and drug use or whether there is something more sinister afoot. When they question the college's enigmatic psychiatric professor Dr Alex Gansa, he proves evasive and uncooperative. The detectives wonder whether Amy's death might be a suicide, but that idea is blown away when a second student is found dead. It soon becomes clear that all of the trial participants are operating under the influence of the experimental drug and that, for them, the lines between love, obsession and madness have become impossibly blurred. As the body count rises, Lewis and Hathaway uncover a web of lies, jealousy and insanity - to which Lewis himself could fall victim.
