Magnum and a group of his treasure hunting friends are held at gunpoint on a cliff top with the one million dollar prize that was the hidden object of a treasure hunt competition, organized to help promote Robin Masters' new novel by using clues from it.

As he and T.C. deep sea scuba dive, Magnum sees a young boy who appears out of nowhere with no breathing apparatus and signals him to follow. Determined to prove that the boy was real, he learns that his vision matches the description of a young boy killed five years earlier in an explosion at sea.
