Sandra Ng is a not particularly good-looking prostitute who makes a living by working twice as hard as anyone else. Trapped in an ATM booth overnight with a would-be thief (Eric Tsang), she tells the story of her life in the sex trade in Hong Kong for the past few decades. Her career follows the economic and social ups and downs of the city itself, but she perseveres. When times are good, she works hard. When times are tough, she works even harder. She never gives up and never loses hope. A message everyone in Hong Kong these days could take to heart. Forget the hooker-with-a-heart-of-gold stereotype, here is a hooker who develops marketing strategies and tries to make a comfortable living by providing a service. Sandra Ng delivers a career-topping performance, unashamed, unrestrained, and so enthusiastic she seems capable of bursting from the screen.
