America's monuments claim authority, carved in stone or cast in bronze, but filmmaker Tom Trinley sets out across the country in a borrowed 1965 Airstream trailer to test what they leave out. He stops at Fort Pillow in Tennessee, the Purchase of Manhattan monument in New York City, Lincoln's Birthplace cabin in Kentucky, the Christopher Columbus statue on Chicago's lakefront, and Mount Rushmore, asking local residents, tour guides, park rangers, and tourists what each site actually commemorates and who it leaves out. Sociologist James Loewen, whose book "Lies Across America" inspired the project, appears on camera as content advisor for each stop, alongside historian Howard Zinn and Smithsonian museum president Lonnie Bunch. The film treats each monument as a claim to be checked against the people whose experiences never made it onto the landscape, and asks a plainer question underneath the history: who protects these myths, and why. A 2023 remastered version updates the original cut with the same itinerary and interviews.
