A man promises to protect a creature that saves his life, then betrays it for a king's favor. That choice, and what it costs him, is the entire story, no wasted time, no moral softening. The spiritual deer doesn't punish him with violence; it lets him drown in the river he swore to protect it from, turning his own desperation into the mirror of his betrayal. Ancient folklore knows something modern storytelling forgot: the deepest guilt comes not from external judgment, but from being forced to live as the person you promised you'd never become.

In ancient times, a Persian merchant loses his way in a windstorm, and a spiritual deer marked with nine colors appears to lead him. Later the deer pulls a drowning man out of a river, and in return he swears never to tell anyone where the creature lives. That man then arrives at an imperial palace, where the king wants the deer hunted down so its hide can be made into clothing. Tempted by greed, the man must choose between his promise and the king's wishes. The film is a supernatural fable about a vow made to a magical creature.
