In the heart of '90s Mexico City, in a world that overlooks the talented sound editor Montserrat, a dark thriller unfolds involving cult horror director Abel Urueta, his neighbor, and Montserrat's long-time unrequited love, the charming but faded soap opera star Tristan. Upon the discovery of Urueta's claim to lift a curse brought upon by a Nazi occultist through a lost magical film, Montserrat and Tristan find themselves entangled in a mission to shoot the missing scene. But as they delve deeper, supernatural occurrences manifest, calling into question the boundaries between their reality and the arcane sorcery that might be more than just cinematic fantasy.
