Magnum, P.I. - Season 3 Episode 1

First part of what was originally shown as a feature-length story. Nuzo, an old war comrade of T.C. and Magnum's, suddenly arrives in Hawaii, and finds T.C. to warn him that Colonel Ivan, a sadistic Russian agent who once held them captive and tortured them in a P.O.W. camp in Vietnam, is after them. At first, T.C. puts his old buddy's fears down to delayed stress, but it gradually begins to seem that there might be some truth in his claims. Meanwhile, Lt. MacReynolds resigns from the Navy, and Magnum lets him stay with him for a few days, but a fatal accident meant for Thomas - as yet unaware of Nuzo's warnings - adds ground to the fears that maybe Ivan is on the trail after all...
