In 1935 Texas, Susannah, an academic and song collector for the Library of Congress, visits a high-security prison where she meets Pearl, an African-American woman imprisoned for murder who longs to leave prison and find her lost daughter. Hoping to record the treasure trove of spirituals and African folk songs that only Pearl knows--and make her reputation on the discoveries--Susannah bargains for Pearl's parole and arranges for several public performances. The two women soon find themselves walking a delicate line between exposure and exploitation. Featuring beautiful a cappella renditions of little-known American folk songs, Black Pearl Sings! chronicles a powerful story about being a woman in a man's world, being black in a white world, and fighting for one's soul in a world where anyone can be a commodity.
