Echoing screams fill a desolate, abandoned factory... Within it appears a woman who has lost all sense of human identity, completely transformed into a dog. She crawls like a dog, eats like a dog, barks like a dog, forgetting everything, obeying only the instincts of a beast. Bound by a heavy chain and a cold collar, her body is surrendered entirely to her master. This bond is stronger than iron, the master-servant relationship now permanently sealed.
