In the maiden voyage of the team’s newly acquired Learjet, the NWIDI adventurers travel to southern Japan to investigate an underwater pyramid off the coast of Yonaguni. After a dramatic landing in the Aleutian Islands of Alaska and a run-in with Department of Justice agents in Tokyo, they finally reach Yonaguni and soon find themselves involved in a case of murder and international kidnapping. In an effort to solve the murder and clear their own names, they uncover a dark secret hidden on the tiny island for more than 10,000 years.
