Drown Among the Dead(Piérdete entre los muertos)

An elderly comedian is buried up to his neck in the Mexican desert. A bitter young woman threatens to pulp his head with a nail bat; the only thing that can stall her are his stories of a mythical threshold behind which lies the absolute truth. Is she in his dream or he in hers? Or were they once the Bonnie-and-Clyde-like couple we keep seeing, exacting their revenge on the world?
