Although Eric Tobin was reported missing in action over eight years ago, his fiancee, Laura Fraser, endowed with ESP, doesn’t believe it. Arriving in Hawaii, where she occasionally has flashes involving Eric, Laura goes to work for Rick at the King Kamehameha Club as a singer. Magnum befriends her and in finding out the truth about Tobin, discovers that he was a highly trained and effective government agent working under the control of a man known only as Delta One. Magnum's search brings him into opposition with the sensitive intelligence organization, resulting in a dramatic preordained conclusion.
