Éter, released in 2015, is a dramatic film that explores identity, work, and social exclusion through a deeply personal story. The narrative follows a transgender woman who achieves her long-held dream of working in a carbon mine, a profession defined by physical hardship and long-standing male dominance.

The film’s central conflict emerges after she undergoes gender-affirming surgery and is suddenly confronted by a powerful superstition that forbids female workers from entering the mine. This belief, rooted in fear and tradition, becomes a barrier that threatens not only her career but also her sense of belonging and self-worth.

Éter uses the mining environment as a stark and symbolic setting. The darkness, danger, and isolation of the mine reflect the emotional struggle of the protagonist as she faces rejection from a system that once accepted her, revealing how fragile progress can be when challenged by cultural prejudice.

The storytelling is restrained and serious, focusing on internal conflict rather than spectacle. Interactions with coworkers and authority figures expose quiet discrimination and moral tension, emphasizing how institutional rules and superstition can quietly enforce inequality.
