This Argentine film freshens up an old cinematic device: juxtaposing science fiction and religion. A Buenos Aires mental hospital is thrown into an uproar when a mysterious male patient appears out of nowhere. As the psychiatrists grill the stranger, he sticks to a story that suggests that his origins are far from earthly. In fact, if his seemingly supernatural powers are any proof, he may well be a space alien. Unable to comprehend the incomprehensible, the authorities decide to lock the visitor away from public view, maybe even put an end to his life--and the analogies to Christ and Christianity are lost on no one.
