The movie is about a guy (called Gyeon-woo) who sees a drunk girl swaying about on a train platform and saves her from possibly falling into the track a train comes. Following that he ends up taking care of her all night, including helping her into a hotel bed. In somewhat conservative Seoul you can't just drag a drunk girl into a motel at night, and soon the police show up and Gyeon-woo is arrested. Soon after she calls him, and arranges to meet him to find out what happened. They end up in a relationship where the girl is clearly in charge, bossing him about, yet he is soon head over heals in love with her.
