Two boys, referred to as Big Master and Small Master, run a blood-buying business from an abandoned church. A homeless girl named Han-Su has unknowingly become involved in their operations. Big Master wants to get rid of Han-Su from the church quickly, as he needs customers and especially her blood. Small Master, on the other hand, is interested in connecting with the human world and uses Han-Su to annoy his brother. Meanwhile, Han-Su just wants to stay away from Big Master long enough to remain in the church until she can afford a place of her own. Each of them has their own needs from the others, but how much time Han-Su has left to understand her situation remains uncertain.
