Synopsis of "Mercy for None" K-Drama
The story follows a Nam Gi Jun, a prominent member of the Bong San Gang, led by Koo Bong San. He fought in bloody turf wars, helping the gang rise to power. However, his life took a dramatic turn when his younger brother, Nam Gi Seok, joined their rival gang, Joo Woon, under Lee Ju Un. To protect his brother, Nam Gi Jun made a brutal decision, he left Bong San for good, severing his left Achilles tendon as proof that he would never return.
Eleven years later, he lives a quiet life running a small drink supply business that serves Bong San-owned establishments. He has no intention of going back to gang life. But when Nam Gi Seok, now the second-in-command of Joo Woon, is found dead under suspicious circumstances, Nam Gi Jun realizes he cannot stay away. To uncover the truth and seek revenge, he steps back into the underworld he swore to leave behind—a world where old grudges still burn, power has shifted, and nothing is as it seems.
