Shing

When Yvet was a child, her uncle forced Yvet to prostitute herself for a client Shing had pimped out.
As Yvet grew up, she pursued Shing's whereabouts as a personal vendetta.
Shing had moved to Macau and made a fortune from casino winnings.
He also bought a struggling casino in return for a favor, which became widely publicized.
When Yvet heard the news, she and Luk went to Macau to take revenge on him.
After a joint struggle with the CIA, Yvet succeeds in interrogating Shing, but discovers that he is a different person who has been replaced.
