Roy Fairfax, a junior partner for timepiece manufacturers Fairfax & Sons, arrives in the quiet village of Slipfold to visit his fiancée Jennifer Peters and seek permission to marry. As he makes his way through the lanes in a gleaming new motorcar, he unintentionally spooks the village dentist Arthur Peters’s horse, setting off a small scramble of startled animals and villagers. At Jennifer Peters’s home, Roy crafts a plan to take her out for a drive and, in a gesture meant to seal the engagement, presents her with a brand-new watch. Yet Jennifer reveals a curious quirk: she never wears a watch because, for her, timekeeping seems to matter far less than the truth of a moment. The watch stops almost immediately, a hint that something unusual may be at work.
As Roy learns more about his beloved, he discovers a family trait that runs through Jennifer’s lineage: the women in her family possess an uncanny ability to halt any mechanical device they encounter. In a tense, somewhat comic test, Arthur lays Roy on a dentist’s chair and scrutinizes him, probing whether he can stand up to the pressures of marrying into a clan whose power hinges on machines ceasing to function. Roy’s attempt to present himself as a worthy suitor falters under the weight of this revelation, and he bolts from the house, his dreams of a smooth London life abruptly unsettled. That night, Arthur and Aunt Mab, the formidable aunt who helps guard Jennifer’s secret, debate whether to tell her the truth, but they hesitate, worried about how such knowledge might unsettle a girl still too young to grasp the full consequences.
The next leg of the tale carries Jennifer toward London, where a group of reporters led by the ambitious Jock Melville, a reporter by trade and a hopeful romantic at heart, are eager to meet her. A train journey becomes a stage for the unfolding drama: the train unexpectedly slows to a halt, and a tree topples onto the track in the wake of Jennifer’s powers. Jennifer and Angela Carew—an enterprising journalist who immediately spots a sensational angle—board a truck for a makeshift escape, while Jock and Angela chase the story from different angles. Later, Jock finds Jennifer again in a cart, and as night falls, Angela’s pursuit of a headline-driven narrative creates a tension-filled chase that keeps the reader (and the audience) glued to the events as they unfold.
In London, Jennifer’s path crosses with her fiancé’s family business when she attempts to visit Fairfax & Sons. A case of mistaken identity lands her with Roy’s father, John Fairfax, who tours her around the factory and showroom. The moment the machines hum into life, Jennifer’s unsettling gift becomes undeniable once again: she can halt the machinery, though the moment is far from calmly meteoric. A dramatic attempt to stop a smash-and-grab robbery ends with Jennifer being bundled into the thieves’ car, which promptly breaks down. The criminals are caught, but Jennifer is knocked unconscious, and when she awakes, the car springs to life again just as her powers falter in her sleep. Jock Melville rescues her, and his article about her intervention turns Jennifer into a subject of feverish public interest.
The journey intensifies as Arthur and Aunt Mab press on to locate Jennifer in the city. They find her roommate Carole Saunders—an air hostess who has occupied herself with a shift the moment Jennifer left—and a tense, racing road trip ensues. They hasten to the airport in a horse-drawn milk cart, fearing that Carole’s plane might take off if Jennifer isn’t there to stop it. They arrive just in time to witness a dramatic Handley Page Halifax taking off with Jennifer, Jock, Roy, and John Fairfax aboard. Panic flickers across faces as the aircraft hurtles toward the horizon; in a courageous turn, Jock parachutes out with Jennifer, and both crash-land safely on solid ground. The following morning, Jock has dispatched a story about the miraculous save, a piece that cements Jennifer’s status as a national sensation and earns him a front-row seat in the narrative wars that follow. Angela remains wary, questioning whether the miracle is truly magical or merely a trick of the moment.
Back on solid ground, Jennifer confronts Jock with a fierce honesty: she is appalled by his sensationalism and the way he used her name for a bigger story. She vows to step away from the glare, but her path back to London is blocked by a wave of public opinion, with trains and buses filled with people who have read the headlines. Carole, loyal and resourceful, helps her navigate the noisy streets, and Angela seizes on another opportunity to test the truth of Jennifer’s abilities by staging a ride by horse and cart. The journey becomes a litmus test: Angela’s accompanying article claims that Jennifer is a fraud if she cannot stop a simple watch, but Jennifer’s powers falter only while she’s asleep, which leads to a broader debate about the reliability of the tests being run by the press.
As the media circus grows louder, the four main figures—Jennifer, Jock, Angela, and Arthur—arrive at a dramatic showdown in the printing press room of the Evening Comet. For fifteen minutes, the press slows, then speeds up, while the crowd waits for a definitive demonstration. It is only after Aunt Mab and Arthur explain the deeper mystery behind Jennifer’s abilities—she can stop machines only when she is in love—that the tension shifts. With that revelation, Jock’s column becomes a playful, reverent defense of Jennifer’s humanity: she is not simply a phenomenon to be exploited, but a person who experiences love and doubt just like anyone else. As Jock writes a final piece about why she “failed” the test, Jennifer and Jock find themselves drawn together in an embrace that feels earned and real.
In the end, love proves to be the true catalyst for her powers, and, on balance, it is love that sustains them through the storms of publicity and public opinion. Jennifer and Jock marry, embracing a life that acknowledges both her extraordinary gift and the ordinary joys of companionship. On the train ride to their new future, a moment of doubt surfaces—the train stops as if answering a lingering question—but Jennifer points out that the stoppage has nothing to do with her abilities. The couple’s union signals a hopeful note for a world where wonder can coexist with responsibility, and where the press—though hungry for a tale—learns to temper its appetite with compassion and respect for the people at the center of the story.
