Plot
John Emmett, an American everyman, is on a fishing and hunting trip when his car breaks down. He is offered a ride by a stranger, Ann Nicholson, who is driving to Santa Fe. She asks him to take turns behind the wheel.

During a stopover a woman identifying herself as a nurse takes John aside in a diner and says she has been following them because Ann is an escaped mental patient of a Dr. Frederick Simmons. And although he is not sure what to believe, John begins to doubt Ann when two policemen attempt to arrest them, claiming to be investigating a murder in Los Angeles.

John and Ann slip away. He demands the truth, whereupon Ann says she is an ex-German citizen who stumbled upon a government plot and is in possession of valuable scientific transcripts embedded on a small cosmetic mirror. In order to prevent Simmons from having Ann committed to a mental institution against her will, John asks Ann to marry him, while also declaring his love for her. They wed in a small town and then continue their journey to find the scientist who wrote the transcripts. The chase ends in a confrontation between Simmons, who is actually a Soviet spy, and his accomplices versus FBI and CIA agents, who verify Ann's story. Ann and John enjoy their honeymoon on the fishing trip John had originally planned.

Critical response
The New York Times wrote that the film was "a rather lax and familiar melodrama about Communist espionage in this country, offers two real jolts. The climax, and this may be an unfair revelation, has a known subversive given some leeway inside a vital guided missile plant. Secondly, the place seems about as inaccessible as a drive-in restaurant. [...] The responsibility, or irresponsibility, must be shouldered by Henry S. Kesler, who handled the screenwriting, the directing and producing, and none of it very well."
