In 1982 an alien spacecraft descends into the Earth’s stratosphere and hovers for months over Johannesburg, South Africa. Humans, alternately fearing that the aliens are hostile and hoping that they are harbingers of technological advances, board the ship. They are disappointed to discover that the aliens are neither, being nothing more than incredibly ill and malnourished refugees from a distant planet. Human governments around the world provide aid for the aliens while they bicker over what to do with them.
