What if South Korea — a country with some of the strictest gun laws in the world — suddenly found itself flooded with illegal firearms? That’s the chilling premise of Trigger. As illegal firearms flood into a gun-free South Korea, a resolute cop and a mysterious partner join forces to stop the chaos from sweeping the nation.
The plot revolves around guns becoming increasingly accessible to Korean citizens secretly, with each recipient having a different motivation — someone struggling with mental illness, a grieving parent who never got justice, a bullied student, a sexual offender seeking revenge on the police, and more. Case by case, the lead unravels the threads, tracing them back to uncover where it all began.
Cast
Kim Nam-gil as Lee Do — a principled ex-sniper and cop
- Kim Young-kwang as Moon Baek — a mysterious and ideologically driven antagonist
- Park Hoon, Kim Won-hae in key supporting roles
Kim Nam-Gil is known for The Fiery Priest and Island; Kim Young-Kwang starred in The Haunted Palace; and Park Hoon is known for Descendants of the Sun.
What Works
Starring Kim Nam-Gil and Kim Young-Kwang, Trigger is gripping from the first moment, rivaling series like The Glory in just how uncomfortable it can make its audience.
What makes Trigger so engaging is the clash between its two leads — on one side, a principled ex-sniper who believes in justice through law and restraint; on the other, a mysterious figure who sees chaos as the only path to fairness, arming the powerless and letting them decide the fate of their oppressors. Their ideological battle gives the drama both heart and tension, and the performances are phenomenal.
Brilliant acting from many actors — Kim Young-kwang especially, but also many side characters shine throughout.
The show also raises real questions. Its message is heard loud and clear if you take the time to look — Trigger helps you understand how not normal it is for gun violence to be a regular occurrence, and how that reality is the worst nightmare of other people.
What Doesn’t Work
The ending felt anticlimactic — we never fully learn what happened to the antagonist, and it’s clear the forces behind him still intend to spread guns nationwide. In the end, very little is resolved, and the final episode lacked tension.
The drama handles some serious topics clumsily, often only showing the high-level impact due to its choice to tackle multiple societal issues within its episode count.
Also worth noting: the show contains extensive, bloody violence, including gory mass shootings and their aftermath. Not for the faint of heart.
Verdict
Trigger is a bold, provocative drama that dares to go somewhere most K-dramas never have. The performances are strong, the social commentary is sharp, and the first half especially keeps you hooked. It stumbles with an unsatisfying ending, but it’s still a worthwhile watch — especially if you enjoy thrillers that make you think as much as they make your pulse race.
