Although Eric Tobin was reported missing in action over eight years ago, his fiancee, Laura Fraser, endowed with ESP, doesn't believe it. 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.

Part 2 of 2. A tragic event which he believed had been successfully relegated to the far corners of his mind, resurfaces and explodes with jolting clarity for Magnum, when he briefly sees a girl he is convinced is his wife, reported dead in the ruins of Saigon.

As Magnum, T.C. and Nuzo plan to get to Ivan before he kills them, the Navy - in particular, Colonel Greene and Admiral Hawkes - have their own concerns and questions regarding Mac's death.

When the indictment against Quang Ki in his attempt to murder Magnum is dismissed, it becomes evident that the villain will stop at nothing to place Magnum's former wife and daughter in deadly jeopardy.
