A West Belfast rap group rails against British imperialism in Rich Peppiatt’s riotous, unruly, comic docudrama. An exhilarating origin story of the real-life band of the title, combining fact with a liberal helping of fiction, it is enthusiastically performed by the rappers themselves in Irish Gaelic. The film was the first Irish-language film to premiere at the Sundance Film Festival, winning an award for its director.
