Song of Tomorrow.

Ivy Ling Po was at the height of her fame in traditional Huangmei Opera films -- and chiefly as a male impersonator -- when she radically changed her image, taking on an ultra-contemporary semi-musical role in Song Of Tomorrow. Ivy plays a dance hostess and leading man Chiao Chuang is a jazz drummer, but with a difference. Chiao is a heroin addict, and Ivy learns that heroin is a far more lethal adversary than "the other woman" when trying to keep their marriage intact.
