The salvage team that went to the moon resurrects an old project: towing an Antarctic iceberg to a drought-stricken island off the California coast. Their plan involves using the Vulture's engines to direct the iceberg's course. The competition is a well-funded and unscrupulous corporation.

Harry and crew run into extreme difficulties in bringing an iceberg to California to be used as a source of water. The engine they use to steer the mountain of ice breaks loose and the iceberg drifts into the shipping lanes.

The Salvage team learns that a herd of wild horses are going to be shot as part of a government program to control their numbers. To save them (and make a profit), they round them up to sell them to a local police department as mounted patrols.

Skip convinces Harry to buy a race horse called ""Harry's Doll"", based on computer predictions that it will be a winner. When the horse breaks its leg in its first race, a NASA doctor is brought in to meld the bone using laser technology. Against all odds, the horse races again with young Michelle as the jockey, but will it win?

When a severe drought threatens a farm belonging to Harry's aunt and uncle in Arkansas, the Salvage team attempts to harvest rain from the clouds using a very unique method: heating the air above the clouds with flame devices mounted on an old biplane.

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.
