Solidarity follows pioneering New Zealand rappers Upper Hutt Posse after they're invited to the United States by the Nation of Islam. They perform signature song 'E Tū' — about Māori resistance against oppression — and take their message of justice to Detroit community station WDTR. In New York, UHP are interviewed by veteran DJ Imhotep Gary Bryd. Later they meet Abiodun Oyewole, from rap pioneers The Last Poets. This is a street level view of urban artists spreading a message of Indigenous and Black unity, and social justice. Solidarity was directed by Rongotai Lomas and UHP lead vocalist Dean Hapeta.

An East Coast community in Ruatōria, New Zealand attempts to live in autarchy according to the tenets of their movement. Bob Marley, a prophet of our electronic age, is the soundtrack to the everyday lives of these Māori who feel closer to their own roots by observing a blend of Afro-Carribean Rastafarianism and the Ringatū faith. Merata Mita's camera respectfully portrays this singular cultural dialogue. The outsider cultures of Jamaicans, Ethiopians and Māori have come together, vibrating to a common cosmic chord. They find an underground brotherhood, across continents and seas.
