A long-unheralded hero of the secret safe-house chain that gave runaway slaves passage to free states and Canada, free-born abolitionist William Still managed the Underground Railroad's Philadelphia way station, and─at great peril─kept meticulous records on the dozens of families he aided to freedom. His efforts and his legacy are brought to light in this compelling documentary. 60 min. Standard; Soundtrack: English Dolby Digital mono; Subtitles: English (SDH); featurettes.
