Plot – Spoilers:
Oh Dae-su is what most people other than his few close friends would describe as obnoxious and annoying. After a drunken brawl that continues into the police station, Oh Dae-su is bailed out by a friend. He stops by at a phone booth to talk to his little daughter but is abducted by unknown people and dumped in a room. For 15 years. When he finally makes it out, he is seething with revenge and questions on why he was imprisoned.

There is not much else to say other than that Oldboy is one of the greatest films a human can ever see.
