Dr. Susan Wheeler (Geneviève Bujold) and Dr. Mark Bellows (Michael Douglas) are resident surgeons in Boston Memorial Hospital and are living together. Her friend is a patient who falls into a coma after surgery. There has been a series of comas in the hospital. Susan starts investigating and stepping on many toes. Mark plays politics and is pressured to reel in his girlfriend. Susan discovers that all the comas come from one operating room and the patients get transferred to Jefferson Institute for long term care.

Michael Crichton directs and adapts the novel by Robin Cook. It's got some very good paranoia thriller vibe during the second half. The first half can be a grind. Crichton is not the best at pushing the pace when the story isn't at its most intense. He could have had some help. Geneviève is not always the most animated actor. Her investigation could have been more compelling. It is an interesting movie with a great twist.
