A lone driver on a long journey to the unknown travels through the American landscape as night is falling. With the approaching monolith of Devils Tower, however, his perception of the passing horizon changes. The film begins to warp into an almost hallucinogenic vision of the afterlife called forth by the mysterious spirit of the mountain. What Happens to the Mountain is an engaging tribute to a sacred landscape, but also a meditation on experiencing one’s own death, with esthetics inspired by literature, late night radio, and ancient legends.
