Oh Dae-su (Choi Min-sik) is a normal family and business man in Seoul, Korea. One night after he was out drinking, he wakes up in a private jail like cell. For 15 years, no one tells him why he's there nor does he remember. In his fairly comfortable room, there is a television set. The only way he can tell what's going on in the outside world. He works out every morning to try and stay fit and aware.
As he is watching the television he hears reports that his wife has been murdered and he is the one being blamed as his blood was found at the scene of the crime. Dae-su realizes when he knocked out one night by gas, blood was taken from him to use just for this scenario. He uses a pair of chopsticks and begins the pain sacking task of digging out of his prison. He is determined to get out and find this enemy that has imprisoned and framed him.
Then without warning, he finds himself released on a roof top full of grass. He is given a large sum of cash and a cell phone but a homeless man on the street. He hooks up with an old friend Mido (Gang Hye-jeong) but he feels he can't even trust her anymore. After more clues, he meets a smooth talking man that tells him he has 5 days to discover who this enemy is and he will kill himself or if he can't, he will kill Mido. There is a gross part at the end.
