Bearing an uncanny resemblance to the mistress of a London-based Chinese Triad boss, an ordinary waitress is trained by the MI5 to infiltrate the gang and bring them down.

SYNOPSIS:

MEI LI works illegally as a waitress in a dive bar in London’s Chinatown. After her father dies in the Snakeheads gang’s punitive raid of the joint where he was a croupier, she must pay off their debts to this very gang who smuggled them into England or end up in their parlors. Moreover, Mei Li’s little sister disappeared in the flow of stowaways when they boarded the ship for England. Therefore, Mei Li has no family; she’s bereaved and at a total loss.

When ALEX, an MI5 officer, approaches her with an incredible offer: a job, the promise to repay her debts, and a UK passport, Mei Li accepts. Hence, Alex begins training her to become an agent but also to impersonate ANNA, the mistress of Mr. WU, the ruthless triad’s Head of the archenemies of the Snakeheads.

Now, MI5’s strategy is to divide and rule the Triads. Posing as a Russian thug, Alex teams up with the Snakehead’s boss, kidnaps Anna, and dictates he keeps her for two weeks without asking for a ransom. The assumed goal is to have Mr. Wu give in to whatever demands by the fortnight's end.

Meanwhile, Mei Li is sent into Mr. Wu’s lair to take Anna’s place in a high-stakes performance that can end at any minute if she makes one tiny mistake. At first, Mr. Wu is fooled. However, as Mei Li carries out Anna’s usual sordid tasks, like managing child prostitutes from China, she falls under Mr. Wu’s spell and mistakes his power over her for protection. Despite Alex’s firm attempts to pull her out, she literally becomes Mr. Wu’s mistress and puts the whole mission at risk.

This is when Mr. Wu becomes suspicious of Mei Li. He puts her to the test, charging her to kill a young prostitute who reminds her of her sister. Mei Li snaps out of it and saves the girl’s life. Concurrently, Anna breaks out of her cell by seducing her guard and stabbing him with his belt prong. While Mei Li searches for Mr. Wu’s notebook, the last crucial evidence she needs to put him away, he comes home, followed by Anna, who gapes at her doppelganger! Although Mr. Wu is stunned by the two identical women, deep down, he feels who the impostor is. But he has the two of them tortured to know who pulls the strings. And when the Snakeheads gang storms in to “negotiate” after Anna’s escape and a battle ensues, the only way out for Mei Li during the all-out gang war is to team up with the woman whose identity she stole.

Ultimately, the mission is a success. Mei Li gets British citizenship and must start with Alex a joint operation with Hong Kong’s Vice Division to stop Mr. Wu’s child trafficking. Also informed that her little sister is alive in Hong Kong, Mei Li views her near future as focused and whole.
