In 1987 Hong Kong, newspaperman Yuen and his girlfriend Chor are drawn into a doomed 1930s romance when the ghost of courtesan Fleur publishes an advertisement in the newspapers, looking for her lost lover Chan Chen-Pang. She has waited in the afterlife for Chan for 53 years and believes he has become lost.
Chan was the playboy son of a wealthy family, but longed to be an actor, met and fell in love with talented, beautiful Fleur in one of Hong Kong's teahouses. Realising their romance would never be accepted, the couple committed suicide by opium overdose in order to be together in the afterlife.
Pragmatic Yuen and Chor become dazzled by the romance of Fleur's story and the ghost's glamorous beauty, but as their search for Chan reveals the truth - that Chan did not die with Fleur, frittered away his inheritance and now lives impoverished as a movie extra - they see the value of their own, honest relationship.
The title refers to a rouge case Chan gave to Fleur, which she returns to the now-elderly, guilt-wracked man, before leaving the living world.
