Rouge (1987)

Fleur is the blue angel in one of Hong Kong's "flower houses" - bordellos and night clubs of the 1930's. A detached and beautiful performer, she falls in love with Twelfth Master Chan, heir to a chain of pharmacies. They agree to a suicide pact. Jump ahead 50 years to modern Hong Kong: Fleur's ghost appears in Yuen's newspaper office, wanting to place an ad to find Chan, who never arrived in the afterlife.
