When Saul and Lena, an aging couple who run a local shop, abruptly make plans to leave town, suspicious Magnum and Rick, who are friends with the couple, investigate; only to arrive at the pair's home to see Saul whisked away in an ambulance after suffering a heart attack. Yet when they check at the hospital, he's not there, and it becomes apparent that Saul has been kidnapped. Magnum houses Lena at Robin's Nest while looking for her missing husband, where she explains that they are Holocaust survivors who are being hunted by neo-Nazis.

Inspired by her recent visions, a new singer at the King Kamehameha Club, hires Magnum to find her fiance, Eric, a Marine listed as Missing In Action. Thomas discovers that Eric was a member of the top-secret 'Delta Section' and is, in fact, still alive. Someone else, however, is searching for him and they are determined to bring him in and keep him quiet, at any cost.
