Oldboy (2003) guide: Park Chan-wook's Korean revenge thriller starring Choi Min-sik. Plot, cast, Philippine release date, R-18 rating and where to watch.

Oldboy Plot: What Is the Movie About?

Oh Dae-su is an ordinary man until the day he is locked away in a sealed room. Nobody tells him why. Nobody tells him who is responsible. Days turn into years, and his only companions are a television, his own anger and the slow passing of time. Then, after fifteen years, he is suddenly set free with no explanation.

The film’s tagline sums up the setup: “15 years of imprisonment, five days of vengeance.” Dae-su now has a short window to work out who stole more than a decade of his life, and why. He keeps track of everything in a notebook and pieces together clues from his past. Along the way he crosses paths with Mi-do, a young woman drawn into his search, and with Lee Woo-jin, a figure tied to the mystery.

What starts as a hunt for revenge becomes a tense, often unsettling investigation into memory, guilt and how far a person will go for answers. This page stays at the premise, so the story’s revelations are left for you to discover.
