Yook Dong-shik (Yoon Shi-yoon) witnesses a murder and rushes to get away quickly when he has an accident that causes him to black out. When he wakes up, he discovers he has completely lost his memory and only has one clue to help him – a murderer’s diary that he’s holding in his hand. With no recollection of the events that unfolded and a complete loss of identity, could the diary possibly belong to him?
