In an intense, and deadly game of Russian Roulette, Jin Pyo takes all but one bullet from his gun and demands that his hostage tells him the names of the others involved in that deadly incident of 1983. There was a bomb that killed the South Korean president and several other high ranking officials.

Yoon Sung and Young Joo are surprised to see each other at the hospital. Since they both arrived at the same time, they are both left with the task of verifying the victim and all of the many suspects involved in the incident.

With a stroke of luck and an act of swift thinking, Na Na rescues Yoon Sung in the National Forensic Service. Na Na's timing couldn't have been better, because Yoon Sung was a mere seconds away from being discovered by the Prosecutor Young Joo.
