Mine Own Executioner (1947)

Pretty Molly Lucian (Barbara White) enlists the reluctant aid of psychologist Felix Milne (Burgess Meredith) in treating her potentially homicidal husband Adam (Kieron Moore), who refuses to see a "real" psychiatrist. Traumatized in a Japanese prison camp, Adam proves to be on the verge of severe schizophrenia. In his risky struggle to help Adam, Felix finds his none-too-functional home life deteriorating, and is unable to help himself as he helps others. The situation rushes headlong to a suspenseful climax.
