3 plastic bags.
Relationship Triangles: the dirty cop, simon yam and his wife; louis koo, the dirty cop, and the gangsters.
3 'vehicles' affected by Lam Suet's tire-puncturing scam.
They get offered $5 million for the gold. Sun Honglei tells them to wait, he thinks he can get a better deal. Later he says that he managed to get the offer raised to $8 million - an increase of $3 million.
In the last scene, did the lights get turned off and on 3 times?
