The Earth is toast. A 67 minute nuclear war has left few survivors, who fan out across space in search of a "Class M" planet. The Scout ship "Utah," the second-to-the-last survey ship, has found an uninhabitable planet and is returning to the fleet of ships after a 7 year quest. The "Pegasus," the final Scout ship, is running low on antimater fuel in it's assigned sector. The crew, which has become quite motley over the 7 year voyage, is less and less motivated when sensors detect a drifting ship of similar design. Where is the ship from? Is there a habitable planet in the target system? Can the crew "keep it together" long enough to complete their mission?
