A young woman, Libby Saul, Ida Lupino lives with her parents on an isolated farm not far from the California coast. Libby is used as a middle-man by a pair who no longer speak directly to each other, and she has developed a stammer that adds a quiet ache to her mornings and evenings. One day, while wandering the coastline, she encounters a group of convicts carving a road along the edge of the sea. She returns for several days, unseen by her parents, watching them from a distance, and she becomes especially drawn to Barry Burnette, a handsome young convict, Dane Clark.
As the convicts press their work forward, they eventually reach the hill that separates Libby’s world from their distant camp and approach the farm in search of water. Mr. Saul, Libby’s father, Henry Hull offers to sell them water from his well, but they refuse and, in a surprising turn, he chooses to give them water for free instead. The foreman goads Burnette into a fight, and Burnette lands a punch on the man who oversees their crew, setting a dangerous, tense mood that threads through the rest of the story. One of Burnette’s fellow workers, Jeff Barker, an engineer freshly returned from service, enters the scene at the Saul home when Mr. Saul invites Barker to dinner in the hopes of a possible match for Libby’s future. Barker, Wayne Morris, proves kind and candid, and Libby’s fascination with Burnette only grows as she wrestles with the possibility of a different life.
Mrs. Saul, Libby’s mother, Fay Bainter, senses a glimmer of hope in Barker’s presence and harbors a quiet wish that Libby might be drawn toward a more settled path. Libby and Barker talk at the table, but Libby’s mind keeps wandering back to Burnette and to the question of what will become of him. Barker tells Libby, bluntly, that Burnette’s fate—if he stays on the wrong side of the law—could be San Quentin, a harsh future she tries not to think about. Barker’s invitation to dance is politely refused by Libby, whose heart is already elsewhere; the moment drives Mr. Saul to an impulsive rashness, and he slaps Libby in frustration. That jolting moment becomes the tipping point: Libby declares that she will not live in this oppressive cycle any longer and runs away that very night.
With Libby gone, the house seems to breathe again as Mrs. Saul rises from her bed to speak with her husband for the first time in years. Libby and her loyal dog retreat to a nearby cabin, where the stormy weather arrives as a catalyst for a new turn in their lives. Burnette, having escaped a prison transport, finds Libby during the downpour and pleads to stay with her. She offers him companionship and a route to freedom, and Burnette opens up about the circumstances of his imprisonment: a fight in the Navy, a drunken robbery, and the accidental death of a man that landed him in San Quentin for manslaughter.
The couple begins to dream of eloping to San Francisco, but Libby’s plans are interrupted when she must return to the farm for clothes and supplies. There she discovers a surprising reconciliation between her parents, who reveal that a posse is actively hunting Burnette. The danger closes in as the posse arrives while Libby remains at the farm, and Burnette, hearing nothing from her, makes his way back to the house that night to check on her. Libby hides him in the barn, and there, under the quiet of the late hour, the two find themselves growing closer—an unexpected and fragile love blooming in danger’s shadow. Libby even deflects a near-discovery by Barker when he goes out to fetch a tire pump, saving Burnette at the last moment.
Suspicion, driven by Libby’s unusual behavior, drives Mrs. Saul to confront the couple, and the couple makes a break for it as Mr. Saul and Barker close in to trap Burnette. Barker tries to intervene, but Burnette shoves him aside and speeds away with Libby in a truck, leaving the rest of the posse to give chase. The pursuit ends tragically when Burnette is shot and dies in Libby’s arms, a moment that Testifies to the peril and the costs of their defiant romance. In the wake of the tragedy, Libby and Barker face the future with a fragile resilience, determined to make a new start together, even as the shadow of Burnette’s memory lingers over them.
