Kam (veteran Hong Kong comic actress Sandra Ng) is making a withdrawal from an ATM on New Year's Eve when she's held up at knifepoint by the desperate Bong (Eric Tsang), who is distressed to learn that Kam doesn't even have enough money in her account to make a withdrawal.
The two agree to leave and go their separate ways, when a power outage traps them in the kiosk. Kam tries to cheer Bong up with an amusing story about her life as a prostitute.
This leads to a conversation that lasts through the night, and flashbacks depict Kam's evolution, from underage fishball girl to popular showgirl (who wins over clients doing a deft impression of Jackie Chan circa Drunken Master) to masseuse to long-in-the-tooth hooker.
Outside historical events converge with Kum's story as she weaves her tale, detailing everything from her encounter with a celebrity (Andy Lau as himself) to her unrequited love for a mysterious gangster, Yeh (Wu Kwan of Stanley Kwan's Lan Yu), to her longtime friendship with a former client, Professor Chan (Tony Leung).
There's also an unplanned pregnancy, which leads to an opportunistic romance with Richard (Felix Wong), a wealthy businessman. This 2002 comedy Golden Chicken, directed by Samson Chiu, spawned a 2003 sequel, Golden Chicken 2. The first film was shown at the Film Society of Lincoln Center's survey Recent Films from Hong Kong in 2004.
