There have been a series of attacks on women walking home in the early hours, and now a woman has been found murdered. Chief Inspector Peter Lawton investigates. His suspicion falls on Edward King, an ex-commando who is engaged to Lawton's sister Joan. He uses Joan to trap King, but King flees. It transpires that King is innocent; the killer is his half-brother Jim.
Kine Weekly said "The exuberant, if somewhat lurid and extravagent, yarn unfolds against bright night-club and realistic nocturnal London street scenes which cunningly create an illusion of scope. For its size it carries quite a kick."[3]
Monthly Film Bulletin wrote: "A second-rate thriller, unimaginatively directed; the cast attempts to make something out of the too-familiar dialogue and situations."[4]
In British Sound Films: The Studio Years 1928–1959David Quinlan rated the film as "mediocre", writing: "Shabby 'B' feature, tiresomely made"[5]
To-Day's Cinema called it an "efficient specimen" of the crime thriller.[1]
