In this precursor to the "reality" series Survivor, the staff of the "Daily Planet" serve as referees for a treasure hunt conducted on a remote island by the three heirs to the fortune of Jonathan Skag (Raymond Hatton). It turns out, however, that the "late" Mr. Skag is very much alive, and is merely testing the mettle of his potential heirs. Naturally, not all of the participants play fair--and the result of this skullduggery could prove fatal to all concerned. Fortunately, Superman (George Reeves) is on hand to make sure that justice is served and the spirit of fair play is upheld, but this time he has to keep his presence a secret.
