Set in the shadows of wartime Paris, this 1940s drama directed by Albert Herman stars Lola Lane, Noel Madison and Howard Banks. When a Soviet secret agent discovers her uncanny resemblance to a dead Nazi spy, she infiltrates the enemy and works to save U.S. ships from German submarines. Assisting her on her mission are French underground agents, along with an American serving in the British armed forces.
American correspondent Mike Malone uncovers a Nazi plot for an uprising of the Arab tribes in Lybia. Pursued by Sheik David and his men, Mike takes refuge in the suite of Nancy Brooks, who is in the British Intelligence. He asks her to hide a gun and escapes through a window. Reporting the affair to British Consul Herbert Forbes, the latter tries to discourage him from further investigation, as the British are aware of the plot and are planning on staging a coup. He goes with Mike to Nancy's apartment, and she denies having ever seen him before. Sheik Ibrahim, next in command of the Arab tribe to Sheik David, is plotting with Nazi agent Yussof Streyer to kill David who is friendly with the British. Mike and Nancy have gone to David's camp, escape from Ibrahim's henchmen, and get back to El Moktar before the Arabs attack the garrison.
