This film presents an amusing narrative thanks to a strong screenplay and the captivating portrayals given by Jean Arthur and Marlene Dietrich. It centers on an American Congresswoman traveling to Berlin after the war to assess the behavior of U.S. soldiers. Her visit leads her into a romantic entanglement with one of them, who is already committed to another woman. A rivalry develops between these two women concerning John Lund, who isn’t particularly appealing. Millard Mitchell provides some amusement as the tired colonel; Dietrich's fans will appreciate the inclusion of several songs, and the story concludes with an unexpected turn. It's possible that there was controversy when this film initially came out. While it doesn’t portray American soldiers favorably—showing them enjoying themselves and engaging in illicit trade within a devastated Berlin—it does illustrate how vital it was for people to find some relief from years of conflict and hardship, all delivered with flair and occasional moments of laughter.
