I'll Get You

When American Steven Rossi, assistant to the recently abducted jet designer Dr. Andre Halas, lands in London, he avoids the immigration department, prompting attention from Inspector Reid of Scotland Yard. As Reid begins to track him by posting his photograph in the newspaper, Steve tries to set up a meeting with German Michael Grand, who earlier had offered him a position designing airplanes in order to use Steve's inside knowledge for Germany. Several contacts later, Steve finally acquires the address of Grand's office. When he goes there, however, he discovers only a hotel room occupied by a woman who introduces herself as Joan Miller, Grand's secretary. Joan soon pulls a gun on Steve and brings him to her boss, Col. Wilkes. Steve explains that he wants to see Grand about the job, and Wilkes, after agreeing to arrange a meeting the following morning, insists that Steve stay in the hotel under Joan's watch. The next morning, however, a nosy neighbor recognizes Steve from his picture in the paper and notifies the police. Steve and Joan are forced to flee the hotel, and return to Wilkes, who identifies himself as British Private Intelligence. Wilkes insists that Steve help catch Grand, who is in London funnelling the kidnapped scientists through an underground route into Germany. Steve agrees to work with Wilkes but asserts that he wanted his photo in the paper so Grand could find him, and now would like to catch the criminal his own way. Wilkes assigns Joan, also an agent, to help Steve. They procure Grand's forwarding address from the hotel doorman, which leads them to Irma Brooks, Grand's real secretary. Irma gives Steve the address of Grand's office and then calls Grand, who is in London, to warn him. The "office" is an abandoned building in which Steve finally finds Grand, who speaks to him through a hole in the ceiling. Just before Grand can shoot Steve, whom he suspects of being a spy, Joan wanders inside and knocks over a railing. The noise causes Grand to run, and when they follow him into the street, he jumps into his car and tries to run them down. Steve returns to Irma, knowing that when she sees him still alive, she will worry for her own safety and so visit Grand. When she does just this, they follow her to a beauty shop. Inside, Joan overhears Grand in a curtained booth telling Irma to arrange another meeting with Steve. The voices then disappear, and when Joan goes back outside, she and Steve are immediately arrested by a constable, who recognizes Steve. As they wait for Wilkes in the police station, Grand's car is found burned, with the bodies of Irma and an unidentified man inside. Soon after, Wilkes informs Reid that he has discovered that Steve is an undercover FBI agent, and together Wilkes, Reid and Steve identify Irma's body but realize that the dead man is probably not Grand. Meanwhile, Grand meets a cohort in a bar to discuss his plans to flee the country. Steve and Joan return to the beauty shop, where they uncover a secret office behind the curtained booth. Grand, who is in the office sending a message on a short wave radio, hears them and burns his documents before running out the back door. Steve bursts in and saves as much as the paperwork as he can, but loses Grand. The police soon begin a search for the receiver of the radio message and discover that one nearby embassy has a short wave transmitter. They tail a suspicious attaché who works there to a hotel by the docks. Steve then visits the docks, disguised as a captain, marking his trail with white chalk so Joan can follow behind in a car. At the hotel, Steve spots Grand and follows him. One of his chalk marks becomes obscured, however, and Joan soon loses him. Meanwhile, Grand notices Steve and ambushes him. As they fight, Grand's gun goes off and Joan informs the police that she heard a shot. Grand escapes but Steve chases him onto a freight elevator, where he beats the criminal into submission. The police arrive soon after and, upon searching the ship to which Grand was heading, find and rescue Dr. Halas. Steve ignores Reid's thanks, embracing Joan instead.
