A Foreign Affair
In 1947, a United States congressional committee which includes prim Phoebe Frost of Iowa (Jean Arthur) arrives in post-World War II Berlin to visit the American troops stationed there. Phoebe hears rumors that cabaret torch singer Erika von Schlütow (Marlene Dietrich), suspected of being the former mistress of either Hermann Göring or Joseph Goebbels, is being protected by an unidentified American officer. She enlists Captain John Pringle (John Lund), another Iowan, to assist in her investigation, unaware he is Erika's current lover.
After seeing Erika with Adolf Hitler in a newsreel filmed during the war, Phoebe asks John to take her to army headquarters after hours to retrieve the singer's official file. In order to distract her, John woos Phoebe, who initially resists his romantic advances but eventually succumbs to his charms.
Colonel Rufus J. Plummer (Millard Mitchell) advises John he is aware of his relationship with Erika and orders him to continue seeing her in the hope she will lead them to another of her ex-lovers, ex-Gestapo agent Hans Otto Birgel (Peter von Zerneck), believed to be hiding in the American occupation zone. Meanwhile, Erika and Phoebe are arrested during a raid designed to catch Germans without proper identification papers at the Lorelei, the nightclub where Erika performs. At the police station, Erika claims Phoebe as her cousin in order to secure her release.
Phoebe, grateful for Erika's intercession on her behalf, goes with her to her apartment, where Erika confesses that John is her lover just before he arrives. Humiliated, Phoebe leaves. Colonel Plummer attempts to reconcile Phoebe and John. John is targeted by a jealous and armed Birgel at the Lorelei, but Birgel is killed by American soldiers who shoot him first. Erika is arrested and sentenced to serve time in a labor camp, and Phoebe and John are reunited.
