Higgins goes on a survivalist trip on an island with a small group of young offenders as part of a program aimed at improving their self-esteem. But he has to call upon his survival skills much more than expected when a planned escape by the boys doesn't go as intended and sees the leader of the trip shot dead, leaving Higgins being hunted down on the island by the three young convicts. Back on the Estate, Magnum, with Rick and T.C., plans to take advantage of Higgins' absence by holding a big party, but the get-together seems ill-fated from the start.

T.C. is giving Thomas helicopter flying lessons when he is shot. With T.C. hospitalized, Mac appears on the scene, "volunteering" his services in running Island Hoppers. But it seems that the assailants were actually gunning for Magnum, after a week previously, somebody impersonated him when trying to blackmail a Mexican Mafia King. With Magnum marked as a dead man as a result of the mistaken identity, confusion and chaos reigns, and as per usual, Mac just happens to be in the middle of it all.
