Synopsis: Tae-in, a young man who never speaks, and Chang-bok, a religious old man, work as the clean-up crew for a crime organization. One day, they receive an order from their immediate superior to take care of an eleven-year-old kidnapped girl Cho-hee for two days. The responsibility to take care of the girl falls upon the mute Tae-in who lives in the outback with a sister of a younger age than Cho-hee. The superior who does the activities behind the kingpin's back gets killed for it, and the duo does not know what to do with the girl.
