Old Boy

One day in 1988, an ordinary man named OH Dae-su, who lived with his wife and adorable daughter, was kidnapped and later waked up to find himself in a private makeshift prison.

Dae-su made numerous attempts to escape and to commit suicide, but they all ended up in failure. All the while Dae-su asked himself what had made a man hated him so much enough to imprison him without any reason.
While suffering from his debacle, Dae-su was shocking when he watched the news and heard that his beloved wife had been brutally murdered.

At this very moment, Dae-su swore to take revenge on the man who had destroyed his happy life. Fifteen years had passed and Dae-su was released with a wallet filled with money and a mobile phone. An unknown man called Dae-su and asked him to figure out why he had been imprisoned.

PLOT:

A man, with a lovely wife and child, wakes up to find that he is locked up in a room/prison for a reason about which he's never told, by someone who he's never told about.

Fifteen years later, he is let go, only with more questions than answers. He spends the rest of the film trying to find out who incarcerated him for all those hellish years and for what reason-and in relation to that...to get revenge!!!
