Harry is hired to launch a satellite into space using his private rocket, but the U.S. government attempts to scuttle the attempt. Meanwhile, Skip, recently rehired as an astronaut, faces deadly cold in outer space when the heater in his space capsule malfunctions.
Harry plans a return to space to salvage a communications satellite, Telcom, that's loaded with gold. While Klinger impounds the Vulture, Skip is trapped aboard an malfunctioning space station, and only the Salvage team can rescue him.
Harry treats the gang to a trip to Hawaii where they find he has other motives. He has arranged for a mining operation into the side of an extinct volcano to retrieve diamonds formed by extreme geologic forces long ago.
