But in Ourselves…
The film opens with Shakespeare’s proverb, and words on the screen announcing that its purpose is to highlight the virtues of psychoanalysis in banishing mental illness and restoring reason.
Dr. Constance Peterson (Ingrid Bergman) is a psychoanalyst at Green Manors, a mental hospital in Vermont, and is perceived by the other (male) doctors as detached and emotionless. The director of the hospital, Dr. Murchison (Leo G. Carroll), is being forced into retirement, shortly after returning from an absence due to nervous exhaustion. His replacement is the much younger Dr. Anthony Edwardes (Gregory Peck).
Dr. Peterson notices that there is something strange about Dr. Edwardes. He has a peculiar phobia about seeing sets of parallel lines against a white background, first displayed in an inappropriate reaction to seeing a diagram drawn with the tines of a fork on a tablecloth.
Dr. Peterson soon realizes, by comparing handwriting, that this man is an impostor and not the real Dr. Edwardes. He confides to her that he killed Dr. Edwardes and took his place. He suffers from massive amnesia and does not know who he is. Dr. Peterson believes that he is innocent and suffering from a guilt complex.
‘Dr. Edwardes’ disappears during the night, having left a note for Dr. Peterson that he is going to New York City.
A heartbroken Dr. Peterson returns to her position at the hospital, where Dr. Murchison is once again the director. After reconsidering her notes from the dream, she realizes that the ‘wheel’ was a revolver and that the man hiding behind the chimney and dropping the wheel was Dr. Murchison hiding behind a tree, shooting Dr. Edwardes and dropping the gun. She confronts Murchison with this and he confesses, but says that he didn’t drop the gun; he still has it. He pulls it out of his desk and threatens to shoot her. She walks away, the gun still pointed at her, and explains that while the first murder carried extenuating circumstances of his own mental state, murdering her as well surely would result in the electric chair. He allows her to leave and turns the gun on himself. Dr. Peterson is then reunited with Ballantyne.
