Bulky Kwang (actor unknown, looks vaguely like Samo Hung) and his cousin
Tian are decorators who live next to pretty mainland whore Feng, who undresses every morning at the window and drives Kwang crazy. The decorators are hired for a job by Lu Lu and her maid Lin (actress unknown) to do up the house where she's kept by businessman Robert. Tian convinces Feng to pay more attention to Kwang, and the two eventually become a loving couple ... until her pimp Yung (actor unknown) starts to get heavy. Meanwhile, there's lots of bed-hopping as Tian fools around with Lu Lu, Robert with Lin, as well as a couple of other guys (though it's unclear couldn't quite follow who or why).
