So Ji Sub Returns with a Vengeance in “Mercy For None” – kdramadiary
A brooding storm of vengeance and raw power awaits in Mercy For None set to premiere on June 6!
Bringing the unforgiving world of noir action back into sharp focus, the newly released teaser trailer and striking key art offer a glimpse into this high-stakes drama, anchored by the magnetic return of So Ji Sub to the action genre after a 13-year hiatus.
He portrays Ki-jun, a former enforcer of the criminal underworld who left everything behind — literally maiming himself by severing his own Achilles tendon — to escape a violent past. Now living in obscurity, he’s forced back into the shadows when his younger brother Ki-seok (played in a special appearance by Lee Jun-hyuk), once a powerful figure in their syndicate, is found dead under suspicious circumstances.
Driven by a fierce need for truth and justice, Ki-jun picks up his signature weapon — a bloodied baseball bat — and begins a merciless journey to unravel the conspiracy surrounding his brother’s death. The teaser imagery speaks volumes: a solitary Ki-jun stands tall in a blood-soaked alleyway littered with the bodies of his foes, signaling the ruthless battles and inner turmoil ahead.
The trailer teases a relentless and emotionally charged manhunt as Ki-jun plows through adversaries with unflinching brutality. From street brawls to close-quarter combat, the series doesn’t hold back on action, keeping every punch, blow, and betrayal steeped in noir intensity.
Alongside So Ji-sub is a powerful ensemble cast including Huh Joon-ho, Gong Myoung, Choo Young Woo, An Kil-kang, Tiger Lee, and Cho Han-cheul — each adding depth and menace to a world riddled with secrets, shifting alliances, and silent vendettas. Special guest appearances by Cha Seung Won and Lee Jun-hyuk further elevate the series’ cinematic allure.
Directed with a dark, stylish flair, Mercy For None promises a harrowing descent into the depths of revenge, where redemption is a luxury and survival is earned one brutal confrontation at a time. It’s a story where loyalty is tested, justice is personal, and no one walks away unscarred.
Stream the explosive premiere June 6, only on Netflix — and remember, when there’s no mercy left to give, all that remains is vengeance.
