October 1987, somewhere outside Lost Souls, New Mexico, on a stretch of highway that seems to loop back on itself. A man named Elias pulls into an all-night diner called the Dust Devil, looking for directions, but finds instead a key—a tiny porcelain key, no bigger than his thumb, left on a napkin by a waitress who says she's never seen it before. That key unlocks something in the desert. Something that was meant to stay buried. Luna tells the story of Elias, the key, and the hole in the ground that shouldn't have been there. A story about the weight of objects that want to be found. Slow, intimate, and dust-choked.
