Dr. Julian Blair has been conducting experiments with research with brain waves. One night, while en route to pick up his daughter from the train station, his wife is killed in a car crash, and Dr. Blair becomes obsessed with using research to be able to remain in contact with his late wife. His colleagues, assistant/Dr. Richard Sayles, and daughter Ann try to convince Dr. Blair, that these experiments are bordering on the occult, by the doctor scoffs them all off. When Dr. Blair's handyman Karl tells his boss of an experience he had with a medium, Mrs. Walters. Dr. Blair goes to the seance that night and uncovers Mrs. Walters hoax, but is convinced that she has extraordinary brain waves. While experimenting using Mrs. Walters, Karl becomes injured, shorting out his brain and nervous system. Shortly after, Dr. Blair (with Mrs. Walters and Karl) moves to a secluded house in Maine to further conduct his experiments, which unnerve the townspeople and the sheriff, who believes the doctor was responsible for the theft of the recently deceased, which Dr. Blair uses as conductors for his experiments. Dr. Blair later becomes convinced that Ann holds the key for communicating with his deceased love, but will he use her before the townspeople storm his house believing him responsible for the death of a local? This B-horror schlock hits on all cylinders, with Karloff giving one of his most strongest performances, only outdone by Revere's ultra sinister portrayal of Mrs. Walters. Very good direction by Dmytryk keeps this one moving with the great horror touches. Rating, 9.
