The film uses footage from Monday, February 20, 1939, and opens outside Madison Square Garden with shots of the New York City Police Department reining in anti-Nazi counter-protesters along with a marquee that lists a "pro-American rally" scheduled on that night, above a National Hockey League match and an NCAA Division Icollege basketball game later in the week. After a procession of flag bearers to a stage decorated with swastika-adorned pennants, U.S. flags, and a portrait of George Washington, a German-accented man leads the audience in the Pledge of Allegiance. Kuhn steps up to the podium and casually remarks about how he is depicted as a "creature with horns, a cloven hoof, and long tail" by "the Jewish-controlled press." As he begins to outline a program calling for a "socially-just, white, Gentile-controlled United States" and "Gentile-controlled labor unions, free from Jewish Moscow-directed domination," a counter-protester rushes on stage in an attempt to attack Kuhn. He is beaten onstage by the Bund's paramilitaries, and as he is hauled away by the police the footage is slowed to focus on him. The footage ends with a rendition of "The Star-Spangled Banner" by a German-accented woman, before cutting to a title card noting that the rally occurred when Adolf Hitler was overseeing construction of Nazi Germany's sixth concentration camp and seven months before the German invasion of Poland and the beginning of World War II.
Background
The documentary was produced using footage of the rally originally intended for newsreels that had never been widely issued due to its controversial content. Many film exhibitors avoided footage of Hitler and Nazism due to strongly negative reactions and even disorderly conduct from audiences. News of the Day never released its footage, while RKO-Pathé News quickly withdrew a newsreel incorporating the footage after deeming it "too inflammatory." As a result, the rally was widely forgotten after the end of World War II. After viewing the footage and expressing surprise at the event's obscurity, Curry was inspired to produce the documentary by the rise of the alt-right in the United States and the August 2017 Unite the Right rally in Charlottesville, Virginia. The footage was retrieved and edited from the National Archives, the Grinberg Film Library, Streamline Films, and the UCLA Film and Television Archive.
