The 1920s were a golden age for world cinema, and this is the story of that age. We visit Paris, Berlin, Moscow, Shanghai and Tokyo to discover the places where movie makers were pushing the boundaries of the medium. German Expressionism, Soviet montage, French impressionism and surrealism were passionate new film movements, but less well known are the glories of Chinese and Japanese films and the moving story of one of the great, now forgotten, movie stars, Ruan Lingyu.
