Tina Morris has persistent visions of her brother Randy, a soldier presumed killed in action in Vietnam. She receives a telepathic message from Randy in Chinese by "automatic writing," a psychic phenomenon in which one receives thought impulses and transcribes them while in a trance-like state. Tina seeks the help of Dr. Rhodes, who believes that Randy may still be alive, and seeking escape from a P.O.W. camp. Unfortunately, somebody close to Randy wants to keep his location a secret, and will use any means, including arson and murder, to hide the truth from Dr. Rhodes.
