Carol asks Magnum for help when a series of strange events lead her to believe that someone is trying to scare her. At first she thinks that she just may be imagining it, but as the happenings turn more sinister, her fears grow. It seems that the threats are connected with the leader of a religious group that her father, also a District Attorney, sent to prison over fifteen years earlier, whom she is about to testify for parole to be denied. Meanwhile, Higgins is expecting a visit of three old friends from Sandhurst, but he isn't particularly looking forward to the visit...

Cynthia Farrell comes to Hawaii to see Magnum, and to see if the two can recapture the magic of their relationship in L.A., but when Magnum is hired by an adult film star, he spends more time looking after his case than he does Cynthia.
