After one of her patients goes into a coma after a routine operation, Dr. Susan Wheeler investigates. She learns that several otherwise healthy patients have met the same fate and then been sent away to a mysterious institute. This is a genuinely frightening medical thriller/drama boasting a strong female lead performance and excellent 70s paranoid vibe. This film does a great job portraying the way healthcare can lose sight of its mission, when providing care isn't treated as more important. It starts off a little slow, but once the plot is set it's filled with great tension and atmosphere. For the most part, the story is really interesting and definitely keeps your attention throughout. The heavy feminist tone in here adds to the overall impact of the film. That creepy institute building and extraterrestrial coma patient room make it even more frightening.
