Pre-war Asakusa was a riotous district of cabarets, dance-halls and brothels - a striking backdrop for Shimazu's story of innocence and experience. Pretty, young Reiko is the new dancer in an infamous theatre troupe, and her fellow performers try to protect her virtue in a land of vice. Meanwhile, an ageing actor wants to be a hero off stage as well as on, and the troupe matriarch Marie has to keep them all together.
