A man left crippled after an operation invites the three doctors he believes was responsible to stay at his mansion. As they are killed off one by one a local crime writer and a psychiatrist help the police discover who is the responsible. The suspects are set up well and there are good performances from Bela Lugosi as the butler, Fay Helm as the sister who may or may not be mad and Irene Hervey as the psychiatrist.
