A fashion reporter is united with a former boyfriend, after a chance meeting, and helps him to track down an enemy spy.
The Monthly Film Bulletin wrote: "Medium-paced British comedy thriller. Despite an obvious denouement and a somewhat disconcerting number of loose ends, the plot builds up a reasonable degree of suspense; and the leading players, notably John Heller as the professional spy, give confident performances."
The Radio Times described it as "an uncomfortable mix of romance and mystery".
Britmovie called it a "light-hearted spy story with a touch of romance."
In British Sound Films: The Studio Years 1928âÂÂ1959 David Quinlan rated the film as "mediocre", writing: "Some thrills, some unintentional laughs."
