After his mother’s death, Mariano embarks on a journey to the sacred lake to fulfill her final wish: for her body to rest in its waters. Along the way, he begins dreaming of a sick girl trapped in silence. In another world, the girl is his niece, who has been left in a catatonic state after a car accident. Medicine cannot explain her condition, and only an ancient ritual may be able to return her soul. In this parallel universe, Mariano has a brother he never knew. He soon realizes that the dreams are not merely visions: they are bridges. The girl and his mother share the same soul.

Ajayu means “soul” in the Indigenous Aymara language.
