A young trans girl growing up in a small Patagonian mining town secures her dream job as a coal miner as soon as she turns 18, challenging an old superstition rooted in a folk tale that for 80 years forbid all women from entering the mine's underground galleries, fearing that their mere presence could trigger a collapse.

Tania learns that her grandmother spent the last years of her life in the loving company of an alien. Together with two friends, she travels through rural Argentina to bring the creature back to its place of origin.
