Synopsis
 A and B, twin girls living in a room without a roof, play the same game everyday under the surveillance of periscopes.

 Program Note
 Twin girls A and B live in a room without a ceiling. They play the same game everyday under the surveillance of a periscope. One night, water leaks from a fireplace into which B enters to find where it comes from. This animated film brings allegory of surveillance, daily routines, and an incidental choice of human beings to break free from them. The monotonous color and repetitive sound evoking that of a pipe being constantly hit amplify sense of boredom and anxiety. (CHO Hye-young)
