The Great Man's Lady (1941)

In Hoyt City, a statue of founder Ethan Hoyt is dedicated, and 100-year-old Hannah Sempler Hoyt (who lives in the last residence among skyscrapers) is at last persuaded to tell her story to a 'girl biographer'. Flashback: in 1848, teenage Hannah meets and flirts with pioneer Ethan; on a sudden impulse, they elope. We follow their struggle to found a city in the wilderness, hampered by the Gold Rush, star-crossed love, peril, and heartbreak. The star "ages" 80 years.
