Archaeologists and historians use cutting-edge technology to investigate and explore some of the biggest mysteries surrounding the Underground Railroad, a secret network that helped enslaved African Americans escape to freedom.

The Underground Railroad was not really a railroad, nor was it always underground. It was an informal network of people and hiding places that helped slaves escape the American South. It extended from the South into the northern states, Canada, the western frontier, and even Cuba and the Caribbean. This documentary remembers the people, white and black, famous and almost-forgotten, who risked their fortunes and even their lives to resist the unjust institution of slavery.

Still was determined to get as many runaways as he could to "Freedom's Land," smuggling them across the US border to Canada. Bounty hunters could legally abduct former slaves living in the so-called free northern states, but under the protection of the British, Canada provided sanctuary for fugitive slaves.
