In the Circular Valley lives a spirit, a mute presence: Atlajala.

Thirsting for sensation, this spirit enters a moth, a panther, an eel, and feels what they feel - the cool darkness of water, the pleasure of a kill.

Centuries old and indifferent to time, it enters man and discovers obsession for the first time.

Yearning to be incarnate as man, it enters priests, soldiers and bandits.

When an adulterous couple arrives in the valley, it slips into a woman. Finally, it feels complete.

But as it possesses her, she grows restless and extreme, and her affair takes a darker, more sinister turn.
