Henry Ford's answer to wartime demand was scale nobody had attempted before: a single factory covering 3.5 million square feet in Michigan, built with architect Albert Kahn, housing an aircraft assembly line half a mile long. The film traces how Willow Run went from farmland to the plant that mass-produced the B-24 Liberator bomber, turning Ford's assembly-line methods, honed on the Model T, toward building heavy aircraft at a rate the Axis could not match. Archival footage and photographs show the plant's construction and its workforce, including the women who filled the line as men shipped overseas, while historians explain how Ford and Kahn's industrial thinking became a deliberate weapon of American strategy. The film frames Willow Run as proof that the war would be decided as much by factory output as by battlefield tactics, and it follows the numbers: the planes rolling off the line, the labor drawn in to keep pace, and the gamble that American manufacturing could simply outbuild everyone else.
