Plot summary
T.C. is giving Magnum 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 somebody impersonated him a week previously when trying to blackmail Pasqual Valez ( Byrne Piven ), a Mexican Mafia kingpin. 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.
