Set your reminders, cancel your plans, and maybe warn your blood pressure, Mercy For None is arriving on Netflix on 6th June with all eight episodes dropping in one glorious, chaos-packed go. This South Korean thriller has earned its 18+ rating fair and square, thanks to unapologetic profanity, relentless violence, and enough moral ambiguity to make philosophers sweat. Viewers are advised to proceed with snacks, emotional support, and possibly a helmet.

Thrills, chills, and questionable life choices in every episode

Nam Gi-jun, once the Bongsan Gang's most formidable enforcer, thought he had left the criminal world behind, after all, severing one's own Achilles tendon is a rather definitive resignation letter. His peaceful life as a beverage supplier is upended when his brother, Nam Gi-seok, now a high-ranking member of the rival Joowoon Gang, meets an untimely and suspicious end. Gi-jun's return to the underworld is less a choice and more a grim obligation, as he seeks answers in a realm where truth is as elusive as a straight answer at a mobster's convention.
