The code of the West is resurrected when a hot-headed young Texan hires Magnum to find his former cheerleader sister.

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.
