Helmed by director Byun Sung-hyun, The Merciless features seasoned actor Sul Kyung-gu (Cold Eyes) and rising star Im Si-wan (The Attorney).
Inmate Jae-ho (played by Sul), who lords over his jail, welcomes an intrepid young inmate, Hyun-soo (played by Im) under his wing. Upon their release from jail, they work hand in glove to seize power in Jae-ho's erstwhile crime syndicate. When the story navigates a series of reveals, suspicions grow and feuds arise between the two.
CJ Entertainment will release the film nationwide next month.
