Ecstatic, drunk, he heads home to his wife and kids, only to end up spending the night in an apartment unit one floor above which belongs to a single woman. The preposterous one-night-stand snowballs into a major event, for which he is reported gone missing on TV. Lost, Jong Sil becomes more involved with the woman, discovering things about her, as their relationship takes an unexpected turn.
