Tae-seok (Jae-hee) is a young man who has nothing to do. He rides his motorcycle to hand out flyers every day and puts them into the keyhole. If the flyers are not taken away after a few days, Tae-seok will pry open the lock and stay there for a while, taking a shower, cooking and taking pictures. In exchange, he will help the host with housework and tidying up the room. Once, he met a woman named Sun-hwa (Lee Seung-yeon) who was tortured by her husband in an empty house. She was bruised all over and her eyes were full of resentment. After escaping, Tae-seok missed Sun-hwa. When he returned to her house, he happened to encounter Sun-hwa's husband abusing her. He immediately took action and took her away. Later, the two of them returned to their previous mysterious life and went to look for empty rooms together. Although they did not communicate verbally, they had a tacit understanding with each other. Once when they entered a stranger's room, they found the body of an old man. They held a serious funeral for him and lived happily in this house. Until one day the old man's son came to the door and they were taken away as murder suspects. Tae-seok was thrown into jail, and Sun-hwa was taken away by her husband. But the story does not end here.
