Two men in adjacent hospital beds - one man is paralysed and the other killed the paralysed mans wife. Min-ho's wife has been murdered and he has been hunting the killer to exact his revenge. He had also attempted suicide many times, with the last attempt leaving him paralysed an hospitalised. When an unidentified amnesiac patient is placed next to him, Min-ho is startled to see it is Sang-up, the killer he had been looking for. Not only does Min-ho have his chance at last to avenge his wife's cold blooded murder, he must also do it before Sang-up regains his memory and recognises him. Immobile and laid up in bed, the clock starts ticking for Min-ho - it's time to kill or be killed.
