As the nation enters the 1920s, Stephen Mather and Horace Albright ally themselves with the automobile to "democratize" the national parks and attract more Americans to them. Nebraskans Margaret and Edward Gehrke begin collecting parks each summer, while Glenn and Bessie Hyde spend their honeymoon in a homemade boat on the raging Colorado River through the Grand Canyon. Horace Kephart, a reclusive writer, and George Masa, a Japanese immigrant and photographer, launch a campaign to save the virgin forests of the Smoky Mountains from destruction by making it a national park.
