In 1997, Little Cheung is a street-wise nine-year-old boy living in a bustling neighbourhood of Hong Kong, just before the reunification with China.

The first half of this film portrays the experiences of a young northern mainland Chinese woman (Fan) temporarily working as a sex worker in Hong Kong. After her 3-month visa expires, the second half of the film focuses on Yan's return to her family and her ex-fiancé in Northeast China and the ways that she invests the money that she has earned.
