A psychologist takes on the daunting task of getting into the mind of prisoners. He must gain the trust and cooperation from a group of men who have no reason to help him and who might enjoy killing him.
Lost Caverns Hotel bellhop Freddie Phillips is suspected of murder. Swami Talpur tries to hypnotize Freddie into confessing, but Freddie is too stupid for the plot to work. Inspector Wellman uses Freddie to get the killer (and it isn't the Swami).
