Jae-Ho is a prisoner. He wields the most power among the inmates and makes rules for the inmates. Jae-Ho is also the #2 guy in a criminal gang outside of prison. He is ambitious enough to go after the #1 spot upon his release. One day, Jae-Ho meets new prisoner Hyun-Soo. Hyun-Soo doesn't follow the rules of the prison and he doesn't submit to anyone. The Merciless will be released from 23 Jun 2017 at Lotte Cinema
