Shock

This post-World War II suspense thriller sets off an emotional roller coaster after the psychologically fragile wife of a POW (Anabel Shaw) witnesses a brutal murder from a hotel window while waiting to be reunited with her husband (Frank Latimer). By the time he arrives, she's nearly comatose with shock. The hotel's psychiatrist (Vincent Price) is called in to help. But just as she begins to recognize him as the murderer she saw, he realizes she was a witness to his crime. So he arranges to take her to his private sanitarium where he and his nurse-mistress (Lynn Bari) can insure that no one takes the young woman's ravings seriously and they can secretly administer enough "treatment" to silence her forever. Meanwhile, her husband and the police begin to suspect that everything is not as it seems and as they get closer to the truth, this complex mystery takes some unexpected twists!
