Tag der Freiheit was considered lost at the end of World War II, but an incomplete print of the film was discovered in the 1970s—the extant footage reveals Riefenstahl mainly reprising the approach she used in Triumph of the Will (1934), though certain more expressionistic sequences clearly presage the more audacious style she would adopt for Olympia (1938).

The camera follows the soldiers from their early-morning preparations in their tent city as they march singing to the vast parade grounds where a miniature war involving infantry, cavalry, aircraft, flak guns and the first public appearance of Germany's new forbidden tank is presented before Hitler and thousands of spectators.

The film ends with a montage of Nazi flags to the tune of the "Deutschlandlied" and a shot of German fighter biplanes flying overhead in a swastika formation.

According to her own testimony, Riefenstahl boldly refused his suggestion and insisted on keeping artistic control over Triumph of the Will.

She did agree to return to the 1935 rally and make a film exclusively about the Wehrmacht, which became Tag der Freiheit.
