A hit-and-run victim is operated on by Dr Fenton, but the patient is later murdered, and the doctor finds himself the prime suspect. The mysterious Della, connected to a horse-doping ring, falls for the doctor and helps him clear his name and expose the villains.
Kine Weekly said "The shrewdly chosen leading players neatly handle the bizarre plot, and their alert team work, amplified by a wide variety of appropriate and realistic backgrounds, leads to an intriguing amalgam of sentiment and homicide. Loose ends are securely tied at the finish, and there is no lack of surprise. Good average British thriller."[4]
Monthly Film Bulletin said "a competently made little thriller, convincing at the time, although some loose ends are left. An amusing character part is played by Vida Hope."[5]
In British Sound Films: The Studio Years 1928–1959David Quinlan rated the film as "average", writing: "Rare coincidence of director, writer (Durbridge) and star (Peter Coke) from radio's famous Paul Temple series. But thriller is fairly ordinary."[6]
Chibnall and McFarlane in The British 'B' Film wrote: "Some brisk direction ensured that the film rose above the average supporting mystery thriller."[1]
