Magnum, P.I.

When Higgins asks his help in finding Robin's latest manuscript after it is stolen, Magnum gets some unexpected help in the case when St. Louis gumshoe Luther H. Gillis arrives unannounced on vacation. They set about trying to work out who is so desperate to get hold of the manuscript that they are willing to resort to attempting to kill Higgins and drugging Zeus and Apollo to get it, in scenes reminiscent of those portrayed in the stolen book.

Magnum ponders his future while paying a visit to his family in Tidewater, Virginia, where he unexpectedly meets his grandfather and considers an offer to be reinstated to the Navy. Thomas returns to Hawaii to ascertain whether former girlfriend Linda Lee Ellison is being stalked, while Rick prepares for his wedding to Cleo. As Thomas and Linda renew their relationship as he searches for her stalker, he becomes increasingly certain that his daughter Lily may still be alive.

As Rick's wedding looms ever closer, Magnum continues his surveillance on Linda to try and catch the psychopathic killer who is stalking her. T.C. faces a reconciliation with his estranged wife. And Magnum gets some surprising news about his theory that Higgins is really Robin Masters, as well as the true fate of Lily.
