Some gifted people went to work on this one, including director Alfred Werker and star Vincent Price, but it doesn't work due to a slow pace and the absence of much movement within the film. There are too many scenes of people plotting evil deeds while a patient lies in a comatose state in bed. This does not make for an exciting movie experience. Nor is the story original, as it is hand-me-down Cornell Woolrich stuff about a young woman who witnesses a murder who is whisked off to a sanitarium by the killer, who just happens to be the psychiatrist who runs the place. The dialogue is mediocre and the actors, aside from Price, none too thrilling. I did like Reed Hadley as a police detective, whose late entry perks up the last part of the movie. He had a quiet, understated presence, and plays off nicely against Price, than whom he is almost as tall.
