Nakee(นาคี)

The villagers wish to burn the mother and Kosakon in order to force Nakee to exit from the cave. About to become a human, Nakee gives up in order to help Kosakon. She becomes a giant snake and kills the bad villagers. Kosakon wishes to be reunited with Kam Kaew but she is now dead. The only way he can help her is to become a monk and to pray for her redemption in next life.
