The hard-boiled drama Mercy for None takes viewers on a chilling journey of one man’s path of vengeance.

The eight-episode series follows Ki-jun (So Ji-sub, Doctor Lawyer, Alienoid, Confession), a former underworld figure who severed his own Achilles tendon to leave that life behind eleven years ago. When his brother, Ki-seok (Lee Jun-hyuk, The Secret Romantic Guesthouse), once the second-in-command of their organization, is found dead, Ki-jun returns to uncover the truth behind, and get vengeance for, his brother’s death.

Mercy for None, a Netflix Series, premieres globally on Friday, June 6, exclusively on Netflix. (You can set a reminder for it now.)

Costars include Huh Joon-ho (Bloodhounds, Missing: The Other Side), Gong Myoung (20th Century Girl, Citizen of a Kind), Choo Young Woo (The Trauma Code: Heroes on Call, Once Upon a Small Town), An Kil-kang (Tale of the Nine Tailed, Watcher), Tiger Lee, and Cho Han-cheul (Gyeongseong Creature, Weak Hero), with a special appearance by Cha Seung Won (Our Blues).
