The police officer tells the director that they're running out of time. They've decided to start an undercover operation tonight. The officer asks the director why he didn't come to the party. He apologizes and says he's not the one who was responsible for the previous operation. The director says he doesn't want to be an undercover police officer anymore. He's decided to become a police informant. The informant will help the police find the target of the new operation. He introduces the city where they'll be conducting the operation. It's called bincheng, and it has a population of 1,19 million. The city is remote, and criminals from all over the world have formed gangs there. There are three people who keep the city running smoothly. One of them is the leader of the tiger gang. The other two are secret profiles. The first one is ruthless and cunning. The second one is unknown to the police. The third one is suspected of manufacturing, dealing, and operating an underground casino. None of the police have been able to capture the third one yet. They need to do something about all the criminals in the city. They want to restore the social values of the city once and for all. The new identity for the informant is wanghao, who was born in 1994. He has two mini-cameras, which will help them track down the target.
