A British agent called Philip Scott is killed in a plane crash near the Turkish border. His wife Joan (Betty McDowall) is concerned by a memoriam in the newspaper signed by a mysterious woman known simply as Diana but no trace can be found of her. She is helped by journalists Pamela Jennings (Clare Owen) and Bill Vernon (Vincent Ball) who is keen to do a series of articles on Scott claiming that he knew him during the war. The pair have both had their flats ransacked and are summoned by security chief Colonel Justin (Geoffrey Toone) who believes that both jobs were perpetrated by a double agent called Harris who is some how connected in the Philip Scott case. Later Joan is approached by the head of an Eastern embassy, Kavali (Peter Illing), who informs her that her husband is alive but has defected to the East. He says that if she wants to be reunited with her husband arrangements will be made to get her out of the country to which she agrees but is all as it seems?
A modest but better than you would expect spy drama from quota quickie specialists, Butcher's Film Distributors, who seem to be enjoying some resurgence of interest in their prolific output of low budget programmers as many of them including this one are finding their way on to DVD. Reginald Hearne's script is at times confusing but for once there is some suspense to be had as Betty McDowall's distraught wife seems to be going along with the enemy agents to join her husband who has allegedly defected. The story is kept moving at a good pace by director Ernest Morris whose career was almost exclusively in b-movies and he is helped a lot by Walter J Harvey's atmospheric black and white camera-work. The acting especially from McDowall and Vincent Ball is good all round.
