The Sting is a 1992 Hong Kong action comedy film directed by Nico Wong and starring Andy Lau, Rosamund Kwan, Simon Lui and Bowie Lam.
Simon Tam (Andy Lau) is a righteous private detective who is working for free for 3 years and 8 months at the behest of his superstitious mentor.
On the second to last day of that period, his assistant Joe (Simon Lui) accepts a case involving missing money and an advance down payment of HK$1,000,000.
The missing money turns out to amount to ten thousand million (i.e., ten American billion) Hong Kong dollars of triad money; both Simon and the triads chase after it.
