The Prowler (1951) – Full Plot Summary & Ending Explained

Read the complete plot breakdown of The Prowler (1951), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.

Webb Garwood, a disgruntled cop with a stubborn streak, is called to handle a troubling report: a peeping Tom observed by Susan Gilvray, whose husband John Gilvray works nights as a radio personality. Webb is not looking for romance, but fate has different plans. He is single and finds himself drawn to the striking, married woman, and what starts as a professional concern soon deepens into a perilous obsession. As the two grow closer, a dangerous chemistry takes root, and Webb begins to bend the rules in a way that threatens to swallow him whole.

The affair accelerates as Webb discovers a sharp, cold calculation behind Susan’s vulnerability: her husband carries a life insurance policy. Seizing the opportunity, Webb crafts a carefully staged ruse to cash in on that policy. He tests the air at Susan’s home, creating the impression of a prowler, drawing suspicion and fear into their lives. After one noisy pretense, Webb, in his official capacity, returns to the address to repeat the ruse, this time with her husband emerging armed. In a calculated act, Webb uses his service revolver to kill [John Gilvray], and then wounds himself with the fallen man’s pistol to fake a deadly exchange of gunfire. The plan hinges on a convincingly ambiguous tableau of crime and self-defense, a performance that begins to blur the lines between duty and desire.

A coroner’s jury is swayed by the story Webb and Susan present, reinforced by their testimonies that they did not know each other prior to the husband’s death. Webb’s partner on the force, though, knows the truth, a truth that quietly gnaws at the edges of their proclaimed innocence. The cover-up appears airtight at first, eluding most scrutiny and allowing the romance to seem legitimate, at least on the surface. Susan’s initial suspicions give way to a fragile trust, and Webb reassures her, casting himself as the unwitting beneficiary of bad luck rather than a calculating murderer. Before long, the pair decide to marry, unable to resist the bond that has formed under the pressure of a scandal they hope to bury.

Not long after the vows, Susan discovers she is four months pregnant. The pregnancy is a chilling revelation: the child’s conception would prove that Webb and Susan lied about their prior acquaintance, and it would expose Webb’s role in the husband’s death as a premeditated act rather than a sudden outburst of violence. With the stakes raised, they flee to Calico, a remote ghost town, attempting to raise the child away from prying eyes and the relentless pull of the truth. The plan is simple in its aim—hide, hope, and endure—but the reality is fraught with fear and moral ambiguity.

As the baby’s birth approaches, Webb forces Dr. Dr. William James to travel to Calico to assist with the delivery. The doctor’s arrival triggers a new crisis: Susan realizes that Webb intends to murder the physician to preserve their secret. In a tense moment of awakening, she warns the doctor, who escapes with the newborn and the Cadillac keys, disrupting Webb’s scheme and sealing the doctor’s role as an unexpected safeguard against further violence.

The revelation that Dr. William James would be drawn into this deadly bind shatters Susan’s trust in Webb. She confronts him with the truth she has uncovered: he not only killed her husband, but he also engineered a plot aimed at silencing those who could reveal the truth. The couple’s fragile alliance fractures as guilt and fear converge. Webb accelerates his frantic search for an escape, using the car’s spare keys and pushing past Susan’s earlier illusions of shared happiness. Now, alone in Calico, she watches the man she once believed in crumble into a desperate fugitive.

The final act tee-ups a crisis of pursuit and consequence. Webb’s former police partner makes a bold, surprise visit, blocking the narrow exit from town with the momentum of a broken trust. In a race against the law, Webb tries to push his way out by forcing the partner’s reversing car, but the sound of approaching police cars signals the end of the road. Refusing to surrender, Webb heads for the hills, a figure cornered by his own choices. When the moment of reckoning arrives, a sheriff’s deputy fires from afar, ending his flight in a stark, final judgment.

This tense tale unfolds as a study in desire, deception, and the costs of an unchecked obsession. The screenplay weaves a noir atmosphere through Webb’s conflicted conscience, the ethical murkiness of a romance born under pressure, and a chain of choices that lead inexorably toward a dramatic, fatal resolution. The characters are drawn with clear motives and moral ambiguities, each decision echoing in the quiet aftermath as the town’s silence conceals the consequences of a love gone dangerously wrong. The film invites viewers to weigh passion against duty and to consider how far one might go when the lure of a forbidden connection becomes an all-consuming force.
