Montserrat is a talented sound editor, but she's been left out of the boys' club running the film industry in '90s Mexico City. And she's all but invisible to her best friend Tristan, a charming if faded soap opera star, even though she's been in love with him since childhood. Then Tristan discovers his new neighbour is the cult horror director Abel Urueta, and the legendary auteur claims he has a way to change their lives ... A breathtaking blend of Mexican horror movies and dark occultism.
