Synopsis:
Clark Kent is sent to an island in the Pacific where the volcano named Boki has begun to erupt. Superman wants to evacuate the island, but the island's owner Boysie Harker will not permit it. Harker forbids Superman from trespassing on his property.

Unable to intercede directly, Superman tries to stop the volcano from underground. Unbeknownst to him, a duplicate of himself made of sand and possessing his powers enters the area. The arrival of the sand creature weakens Superman preventing him from stopping the eruption. He is able to delay it instead by diverting a nearby storm.

Superman is then weakened again and falls from the sky. He lands on Harker's ship just as the businessman was preparing to fire on United Nations rescue ships. Superman finishes helping with the evacuation. Harker is arrested. Inside the bubbling volcano, the sand creature begins developing features which resemble the Man of Steel.
