An angry VIP client at Black Sun puts the security team on edge. The security team gets a second chance to make another delivery. Only this time, Do Gi joins the team. What he learns is shocking. Meanwhile, Seong Cheol digs into Ha Jun's past.

While Do Gi wakes up from getting drugged, the bishop comes back to Korea. Now that Do Gi has evidence of how Black Sun is circulating drugs, he sets up a plan. Meanwhile, Ha Jun notices that Rainbow Transport is on Black Sun's tail. Knowing how skillful Do Gi is, he takes every precaution he can.

Rainbow Transport takes in another client. However this time, it is a set-up made by the Bishop and Ha Jun. Not knowing that it is a trap, Do Gi blindly goes into Jangsan Correctional with Gyeong Gu and Jin Eon to save a victim. The only thing that is waiting for him is Ha Jun's trap that will break Do Gi into pieces.

Do Gi goes into Jangsan Correctional as an undercover inmate. He fights all the way through every trap that Ha Jun has prepared for him. Although he barely makes it in one piece, he saves Lee Si Wan.
