“HARRIET TUBMAN: VISIONS OF FREEDOM”

This year marks the 200th anniversary of Harriet Tubman’s birth. In honor of her legacy, PBS presents a documentary “Harriet Tubman: Visions of Freedom,” a portrait of the woman known as a conductor of the Underground Railroad. Nicole London, the film’s co-director and producer, joins us to explore what motivated Tubman to become one of the greatest freedom fighters in our nation's history.
