A group of people surviving since the Mega Disaster from a World War start a new age and live helplessly underground in a tunnel. Devi, the heroine, lives alone in an underground bunker with the only window toward the outside world. One day she hears some sounds from the outside through the window and comes across a living human being from outside for the first time. She meets M, a leader from the outside world, and gets out of her inside place and smells the outside air for the first time. It is a Sci-fi genre that women directors rarely try and an allegory on a human being gradually isolated in their own room or other space like an island. (KIM Sunah)
