A romantic drama, Bolei chi sing/City Of Glass begins with a car crash, in which Raphael (Leon Lai) and Vivian (Shu Qui) are killed in London on New Year's Eve. The two were lovers, but both were married to other people. Raphael's son and Vivian's daughter, both adults, meet in Hong Kong to collect their parents' remains, and as the two get to know each other better, we learn more about Raphael and Vivian's relationship in flashbacks that trace the past 25 years. Director Mabel Cheung uses the relationships of these two couples as a metaphor for the changes Hong Kong went through over the past three decades.
