1983, northern Chile. Lidia (7 years old) lives in an isolated mining town, which is being threatened by an unknown sickness. It has already killed several men and, according to the locals, it's transmitted when a man falls in love with another man. Only through a gaze. Her adored brothers, Alexo (23 years old) and Nicolás (15 years old), are suspected to be carriers of the sickness and therefore they're blindfolded and put in quarantine. Lidia sees that the townspeople begin to harass them, and their father, Gastón (43 years old), exposes them to humiliating public situations trying to prove that they are not ill. Everyone starts to believe them, however, things get complicated when Alexo catches a cold and cannot get better for weeks. This pushes Lidia towards a confrontation with her father and the townspeople who are immersed in the windstorm of a local myth, in order to get help.
