The story of a vital national protest movement: Rock Against Racism, formed in 1976, prompted by 'music's biggest colonialist' Eric Clapton and his support of racist MP Enoch Powell. Fresh interviews blended with archive footage recreate the hostile environment of anti-immigrant hysteria and National Front marches. The campaign grew from Hoxton fanzine roots to 1978's huge antifascist carnival in Victoria Park, featuring X-Ray Spex, Steel Pulse and The Clash.
