British Intelligence (1940) Margaret Lindsay

During World War I, Franz Strendler, a master German spy has cost the British dearly. In desperation, they send for their best agent, currently undercover in Germany. Pilot Frank Bennett is sent to pick him up, but the Germans are forewarned and Bennett is shot down. Luckily, he survives and is rescued by friendly soldiers. While recovering in a hospital, Bennett is tended by a pretty nurse, Helene Von Lorbeer. He tells her he loves her, but she informs him she is leaving, and they will not see each other again. However, after Bennett falls asleep, she kisses him on the cheek.
