The 1904-1914 construction of the Panama Canal, the 50-mile link between the Atlantic and Pacific oceans, is recalled via archival footage, photos and interviews with workers, as well as insights from historians. The undertaking cost the U.S. about $375 million and 5609 workers (out of 56,307), who perished from both accidents and disease. The documentary also explores what life was like for the workers, who were a mix of Americans, Europeans and West Indians.
