Peter Tosh found international fame alongside Bob Marley as a member of The Wailers. As a solo artist he released several landmark reggae albums and even recorded with the Rolling Stones. But he was more than just a successful pop star: he was a revolutionary and a hero to many of Jamaica's poor. He spent his life as a strident campaigner for civil rights and for the legalisation of marijuana. He was more militant and political than his former band mate and his uncompromising arrogance often landed him in serious trouble. For that reason, as this documentary reveals, his life could be as brutal as the way it ended. Grammy award winning film-maker Don Letts explores his career.
