Autumn, 1925 and residents of the Black Hills mining town of Keystone, South Dakota are excitedly awaiting the start of nearby Mount Rushmore, one of the most ambitious carving projects the world has ever known.

But two vicious murders, the discovery of a Bootleg whisky operation linked to Chicago mobster Al Capone, and the kidnapping of Hot Springs Star reporter Minnie Thompson are threatening to derail famed sculptor Gutzon Borglum's epic plans. Enlisting the help of fearless biplane pilot Kallie Sinclair and a host of Keystone volunteers, including Ben Black Elk-one day to be known as "The Fifth Face on Mount Rushmore" -U.S. Marshal Al Twocrow finds himself on a collision course with the outlaws and a monumental showdown at the place the locals call, "The Devil's Thumb."
