Exiled from his native South Africa, South African jazz legend Hugh Masekela is pulled between two worlds. In the late 1980s, the Anti-Apartheid Movement, led by his mentor and fierce Anti-Apartheid advocate Archbishop Trevor Huddleston, launches a boycott against Hugh’s friend Paul Simon over his township music-inspired album 'Graceland', accusing Simon of violating the United Nations’ Cultural Boycott. Miriam ‘Mama Africa’ Makeba joins forces with Masekela — who sees music as a powerful weapon in the struggle — to create the Graceland band, a supergroup designed to bring South Africa’s voice to the world.
