Driven to distraction by a dog yapping endlessly in a nearby apartment, Yun-ju (Sung-jae Lee) -- a college lecturer who's already stressed by his pregnant wife's (Ho-jung Kim) nagging and his slim chances of landing a professorship -- takes action to silence the animal. Soon other dogs in the apartment complex fall strangely quiet, and the landlord's bookkeeper (Doona Bae) sets out to find out why. Joon-ho Bong directs this dark comedy.
