Oh Dae-su is an ordinary Seoul businessman with a wife and little daughter
who, after a drunken night on the town, is locked up in a strange, private
“prison” for 15 years. No one will tell him why he’s there and who his jailer
is, but he is kept in reasonably comfortable quarters and has a TV to keep him
company.
Watching TV though, he discovers he has been framed for his wife’s murder and
realizes that, during one of the occasions in which he’s knocked out by gas,
someone has drawn blood from him and left it at the scene of the crime.
The imprisonment last for 15 years until one day when Dae-su finds himself
unexpectedly deposited on a grass-covered high-rise roof. He’s determined to
discover the mysterious enemy who had him locked up. While he’s eating in a
Japanese restaurant, his cell phone rings and a voice dares him to figure out
why he was imprisoned.
