Old Boy, 1

Ten years ago, Goto was kidnapped. He has never found out who did it or why. Since then he has remained locked up in a private prison and his only contact with the outside world has been a television and the voices of his jailers. He has practically lost his mind and so many years of isolation have transformed him into a different person, a lethal being. One day, however, he wakes up to find himself out in the open. Goto does not know the reasons why he has been released, but he knows that the time has come to plot a terrible revenge. After starting a bloody search, Goto is getting closer and closer to finding the clue that reveals the identity of his torturer and will try to discover the reasons that led to his kidnapping.
