Frank Taylor, Humphrey Bogart, is a Midwestern factory worker who hopes for a promotion but is passed over in favor of a younger Polish immigrant. Frustration gnaws at him as the personal disappointment fuses with a growing sense of belonging he finds in the Black Legion, a secretive hate group that operates in the shadows. As Taylor slips into the Legion, the group dresses in black hood and robes, and he becomes part of a torchlit raid that drives the immigrant and his family from their town, a brutal display meant to enforce a violent social code.
The moment seems to lift Taylor’s fortunes: he secures a promotion and returns to a life that appears to be on the upswing. Yet a factory accident changes everything, costing the company an expensive machine and leaving Taylor to shoulder the blame. In a harsh turn, he is demoted in favor of an Irish co-worker, Mike Grogan, and his sense of betrayal deepens as his personal and professional worlds collide. That same night, the Black Legion abducts Grogan and ties him to a tree, subjecting him to a grim torture.
Ed Jackson, Dick Foran, a trusted coworker and friend, grows suspicious that Taylor stands at the center of these anti-immigrant attacks. He shares his concerns with Ruth Taylor, Erin O’Brien-Moore, who confronts Taylor about the consequences of his actions. Taylor’s response is chillingly violent, and Ruth’s mounting fear drives her to leave him. As Taylor’s Black Legion life intensifies, he descends further into drinking and a damaging affair with a woman of ill repute, while his friend Jackson watches with mounting alarm. Jackson’s loyalty to his friend is tested as he considers reporting the truth, and Taylor, fearing exposure, betrays him to the Legion’s leadership.
In a tense, heartbreaking sequence, Taylor orders Jackson’s capture to prevent his possible police report. Jackson is kidnapped and, after a tense escape attempt, is killed by Taylor in a panic-driven act. Taylor is soon arrested for Jackson’s murder, and Ruth returns to help him at the trial. The Black Legion’s lawyers apply pressure on Ruth and her family, adding another layer of coercion to the courtroom drama. But, moved by remorse and self-loathing, Taylor ultimately chooses honesty, breaking with the faction and telling the truth in court.
The courtroom becomes the stage for a hard-won confession, and the consequences are swift and sweeping. The trial exposes the gang’s crimes and the real cost of hatred, with the judge presiding over a verdict that rings through the town. All local members of the Black Legion are sentenced to life in prison, including Frank Taylor, marking a devastating turn from security to accountability and underscoring a stark, cautionary arc about the seduction and ruin of hate.
