Oldboy is a 2003 South Korean film directed by Park Chan-wook that tells the story of Oh Dae-su, a man imprisoned for 15 years without knowing why. When he is suddenly released, he sets out on a brutal path of revenge, only to uncover a horrifying truth that shatters everything.
The movie starts with Oh Dae-su, played by Choi Min-sik, drunk and arrested on a rooftop. That night, he vanishes into a private cell where he stays locked up for 15 years. His captor feeds him through a slot, plays him TV news of world events, and brushes his teeth remotely. Oh Dae-su keeps a daily tally on the wall, growing more desperate. He even tries to kill himself by hanging, but the guards revive him each time. For years, he pounds the walls, trains his body, and fantasizes about freedom.
One day, a box of food arrives with a clock ticking down. Oh Dae-su smashes through the wall and escapes into the real world. He has five days to find his captor, or the person closest to him dies. Confused by modern life after so long inside, he visits a raw fish restaurant that delivered his meals in captivity. There, he meets Mi-do, a young chef who helps him. They grow close, and she lets him stay at her place.
Oh Dae-su tracks clues using a suicidal man he saves and a beggar he pays off. He finds hints pointing to a rich man named Lee Woo-jin as the mastermind. Along the way, brutal fights break out, like the famous hallway scene where Oh Dae-su takes on multiple thugs with a hammer. His rage drives him forward.
The big reveal comes at Lee Woo-jin’s lavish rooftop party. Lee shows Oh Dae-su security footage from years ago. Back in high school, Oh Dae-su drunkenly told classmates a secret he overheard: Lee Woo-jin’s sister, Lee Soo-ah, was sleeping with her brother. The gossip spread, leading Soo-ah to kill herself in shame. Lee Woo-jin, obsessed with revenge, imprisoned Oh Dae-su to make him suffer the same pain.
But the twist goes deeper. The woman Oh Dae-su has fallen for, Mi-do, is his own daughter. During his captivity, his wife was murdered, and baby Mi-do was given up for adoption. Lee Woo-jin manipulated their meeting to force Oh Dae-su into an incestuous relationship. Oh Dae-su collapses in horror as the truth hits.
Lee Woo-jin offers a deal: cut out his own tongue to prove repentance, and Mi-do lives free, never knowing. Oh Dae-su does it with scissors, blood pouring. Satisfied, Lee Woo-jin walks away but then shoots himself. Oh Dae-su reunites with Mi-do, pretending nothing happened, as they walk off together in a twisted, uneasy peace. The film leaves you questioning if true revenge ever heals.
This ending shocked audiences worldwide, winning praise at film festivals for its raw power.
