In a quiet Kentucky house, Jack Brookfield keeps a late-night gambling circle running, a secret ritual that sits at the edge of respectability. His daughter, Nancy Brookfield, has fallen for Clay Thorne, a young Northern architect whose future seems tied to the Brookfields’ world. Brookfield’s mother—an old Baltimore friend—arrives with the hope of steering her son away from vice. When she sees Brookfield in the garden with his daughter, she appears reassured, and Brookfield proclaims that the gambling for that evening is over, signaling a fragile peace for the moment.
After the guests depart, a spark of mystery flickers to life. Lew Ellinger, a familiar customer, bets on a poker hand and presses Brookfield to join regardless of his claim of not gambling. Brookfield nevertheless plays along, and in a startling moment, tells Ellinger exactly what cards he holds. When Ellinger insists on looking again, Brookfield reciprocates with an almost uncanny honesty about what Ellinger sees, though Brookfield himself cannot fully explain how he can divine the hand. The revelation unsettles Ellinger, who asks how this feat is possible. Brookfield admits he cannot truly explain it, and the gift—this odd, burdened ability—has kept him from gambling, which saddens Ellinger deeply.
Outside, the town’s police chief gathers his men to raid Brookfield’s house, but the raid yields nothing—no cards, no games, no proof of wrongdoing. Inside, Nancy heads to bed, and Clay grows uneasy when he notices a cats-eye ring— collateral once offered by Ellinger—on Brookfield’s finger. The small symbol becomes a test of Clay’s nerve and a reminder of the power Brookfield unknowingly holds.
Brookfield then receives a visit from Frank Hardmuth, a man with a grudge who wants to boss the town and dictate who is worthy of Nancy. The confrontation turns physical when Brookfield punches Hardmuth and warns that one day a man will come into his office and shoot him. Clay overhears, and Brookfield’s reassurance—that his fear is irrational—does little to ease the fear he secretly harbors. In a moment of unintended manipulation, Brookfield hypnotizes Clay, a talent he does not fully comprehend or intend to wield.
The last visitor of the night is Judge Martin Prentice, whose steady, compassionate nature offers Brookfield some relief about his gift. Prentice cautions Brookfield about the perils of using hypnotism, suggesting that hidden powers bring equally hidden risks.
Tragedy soon follows as Clay travels to Hardmuth’s office and shoots him dead, unaware of the full consequences of his actions. With Hardmuth dead, the family insists on a defense, but hypnosis is dismissed by others as a credible basis for a defense. The question of who should defend Clay becomes urgent, and the family turns to Prentice, hoping he will understand the case. Prentice, initially reluctant, is persuaded by the ghostly memory of Margaret Price—the late Mrs. Thorne’s mother and Prentice’s former love—to take on the defense.
The trial unfolds with difficult testimony and limited hope. Even Dr. von Strohn, a renowned expert on hypnosis, struggles to sway the jury. In a desperate gambit, Prentice has Brookfield hypnotize the openly skeptical jury foreman into firing a gun at the district attorney—though the weapon is loaded with blanks. The gambit pays off in a perverse sense, and the jurors render a not guilty verdict, allowing Clay Thorne to walk free.
The film closes on a note that blends the uncanny with the courtroom drama, leaving the audience to ponder the limits of mind over matter and the cost of a man’s hidden gifts. The town breathes a cautious sigh as the truth of hypnotism—whether a blessing or a burden—lingers in the shadows, long after the jury’s verdict.
