The untold story of how a motley crew of punks and reggae artist got together in 1976, using music to oppose racism by founding Rock Against Racism (RAR). Winner of the London Film Festival's documentary award the film blends fresh interviews with queasy archive footage to recreate a hostile environment of anti-immigrant hysteria and National Front marches. As neo-Nazis recruited the nation's youth, RAR's multicultural punk and reggae gigs provided rallying points for resistance.
