Narrated by Orson Welles, this 1978 made-for-TV movie stars Cicely Tyson as Harriet Tubman, who founded the Underground Railroad. At the risk of being recaptured, the abolitionist and former slave helped hundreds of enslaved African-Americans find their way to the freedom of the promised land: the northern states. Tubman also conducted reconnaissance for the Union Army and later became influential in the women's suffrage movement.
