With layered storytelling, sharp performances, and a suspenseful plot, Regai delivers a gripping experience for fans of crime dramas.
A Sinister Medical Conspiracy at the Core
At the heart of Regai lies a disturbing mystery surrounding the deaths of clinical trial participants.

As the investigation deepens, each clue reveals a more unsettling reality—one that blurs the line between science, ethics, and crime.

Vetri’s pursuit of the truth forms the emotional and narrative backbone of the series, offering viewers a strong protagonist who anchors the story with intensity and conviction.
