He comes to consciousness in a strange room which looks like an improvised prison. Oh Dae-Su is pestering himself with questions why he happened to get here and who needed to steal him, but finds no answers. A year later from a news report he finds out about his wife’s death. And what is the most horrible; he is considered to be her murderer. Only in fifteen years of the imprisonment he, at last, gets long-awaited freedom… Will he succeed now in searching for the reason why he has wasted the best part of his time?
