## What Is Nightmare About?

*Nightmare* follows vigilantes who trap villains — those beyond the reach of the law — not in reality but inside nightmares. Set in a unique world that blurs the line between dreams and reality, the series introduces a new kind of justice. Instead of sending criminals to real-world prisons, they are trapped in dreams, creating a hell they cannot escape until death.

It’s a premise that’s equal parts *Inception* and crime thriller — with the moral complexity of vigilante justice layered underneath. The concept alone makes this one of the most original K-dramas currently in development.

## The Two Lead Characters — A Dangerous Partnership

Kim Nam Gil stars as detective Kim Tae Yi — after a long undercover assignment, he returns a changed man, with his personality, speech, and lifestyle transformed, but his determination to pursue evil remains. With sharp instincts and a fierce edge, he teams up with vigilantes who create nightmares to hunt criminals.

Lee Yoo Mi plays Jang Gyu Eun, a police officer in the Southern District who focuses on supporting victims. In everyday life, she is timid and shy, but in dreams, she becomes a different person — entering the dreams of criminals who have escaped punishment and inflicting pain in brutal ways, acting as a “nightmare designer.” [Express & Star](https://www.expressandstar.com/entertainment/2026/03/04/peaky-blinders-filming-locations-you-can-visit-as-the-immortal-man-hits-cinemas/)
