Dae-Su is an obnoxious drunk bailed from the police station yet again by a friend. However, he’s abducted from the street and wakes up in a cell, where he remains for the next 15 years, drugged unconscious when human contact is unavoidable, otherwise with only the television as company. And then, he is suddenly released. In a twisted game of cat and mouse, he has only five days to retrace his past, track down his captors, and get his revenge.
