Part 1 The past comes back to haunt T.C. when an old war buddy named Nuzo arrives claiming that Ivan, the brutal Colonel who held them captive in a Vietnamese P.O.W. camp, is after them once again. Initially, T.C. doesn't take the warning seriously, but after Mac is killed, he and Magnum soon find themselves in a heart-pounding race against the clock to find their would-be killer before he finds them. Part 2 As Magnum, T.C. and Nuzo plan to get to Ivan before he kills them, the Navy - in particular, Colonel Greene and Admiral Hawkes - have their own concerns and questions regarding Mac's death. But things are not as previously thought about Nuzo, and not only is T.C.'s life in great danger, but many other people's too, namely a Japanese prince.
