At the start of the 1920s, Stephen Mather and Horace Albright push for more park visitation in order to convince Congress to provide funding. They use the automobile to further their cause, and by the mid 1920s, park visits are up to 2 million. The stories of two couples, Margaret and Edward Gehrke, and Glen and Bessie Hyde, and their relationships with the national parks, are featured. A national campaign is undertaken by Horace Kephart and George Masa to protect the last stands of virgin forest in the Smoky Mountains. With the help of John D. Rockefeller, Jr. and newly-elected president, Franklin Roosevelt, the Great Smoky Mountains National Park is established.
