Ad-lib Night (아주 특별한 손님, 2006) is the third film by South Korean director Lee Yoon-ki. It tells the story of a group of boys from the country who have come to Seoul to find the runaway daughter of a dying man to be with him on his death bed. The film, based on a short story by Japanese writer Asuko Taira, debuted at the 11th annual Pusan International Film Festival.

Yoon-hee is so harassed by her husband's obsession and frantic love, that even breathing is painful to her. One day, her sudden suicide attempt is foiled when someone takes her in his arms and saves her. Hyung-jun is a rough-looking detective. He asks nothing, but maybe he knows that for some people, just being alive is hard enough.
