The stories played in Khon presentations are invariably those of "Rama", a reincarnation of the Hindu god Vishnu who is the hero in the Hindu epic Ramayana and its Thai version Ramakian.

A greater part of the epic is concerned with the protracted war between Rama the righteous king and Thotsakan the king of demons, which is touched off by the abduction of Rama's beloved consort by the Demon King. The drama is therefore full of love, magic and war scenes.
