This film follows marine historians, archeologists, divers, and artists as they explore the depths of the ocean surrounding Bikini, a unique atoll in the Pacific, in search of sunken World War II ships that were destroyed in the Operation Crossroads atomic tests during 1946. United States aircraft carrier, “Saratoga” and Japanese battleship “Nagato” are two of the famous, yet hazardous, sites explored in this film. Although the United States government promised to take care of the nearly 200 inhabitants that it removed from the island in 1946, the families still live in their so-called temporary home on a tiny nearby island almost fifty years later. The divers try to help Bikinians explore the sunken treasures in hopes that the residents will become experts on the underwater reservation and someday return to their native island.
