Our exclusive clip from Well Go USA's Korean thriller New World shows just how dangerous being an undercover cop can be. Lee Jeong-jae stars as Ja-sung, a cop who has been undercover for the past eight years as the right-hand man to the Goldmoon crime syndicate leader. After the leader's death, the cops launch a new initiative that puts Ja-sung's life in danger, fearing he will be exposed as a mole. Take a look at this scene where Ja-sung confronts his police handler Kang (Min-sik Choi), revealing he needs to get out before it's too late.

The head of the Goldmoon crime syndicate is dead, leaving his top two lieutenants. Seizing the opportunity, the police launch an operation called New World, with the perfect weapon. The boss' right hand man, Ja-sung (Lee Jeong-jae, The Thieves), has been a deep-cover operative for 8 years, closely watched by handler Police chief Kang (Min-sik Choi, Oldboy). With a baby on the way, and living in mortal fear of being exposed as a mole, Ja-sung is torn between his duty and honor as a cop, and the fiercely loyal gang members who will follow him to hell and back.

Using inside information from Ja-sung to damage the relationship between the two feuding contenders, suspicions grow that a traitor lives in their ranks. Ruthless Jung (Jeong-min Hwang, Blades of Blood) escalates the game by hiring hackers to search the police database. As Operation New World closes in, and with the stakes climbing higher and a gangland bloodbath guaranteed among those that remain, Ja-sung makes a final, shocking decision no one could have predicted.
