Deep in the mountains there is a temple where two monks -- Hyegok, an old Zen master, and Haejin, an orphan boy -- live together. One day, a new young monk, Kibong, visits the temple. As he finds himself unable to resist the earthly world, Kibong wants to be taught by Hyegok. Kibong and Hyegok share a spiritual communion. Kibong is continuously exposed to penance and self-mortification, but he can't set himself free from the inner conflicts and his earthly desires.
Hyegok knows that he is old enough to prepare for his death. He asks Kibong to cremate his body in secret, and Kibong does so. When it is all done, Kibong passes on what Hyegok left to Haejin and leaves the temple. Haejin asks him where to go. Without a word, Kibong looks up to the sky. The night comes, and Haejin is left alone in the temple. Haejin makes a fire in the furnace and burns all of Hyegok's keepsakes.
