Knight of the Juggernaut, Pt. 1 & 2
A team of mechanics, capable of a miracle, rebuild K.I.T.T. after it is completely demolished by the juggernaut in a plot to steal a powerful new isotope. Michael and K.I.T.T. have a new mission which consists of guarding a new substance. It was inadvertently produced in the laboratory of a Foundation-sponsored organization, and it is a mysterious and powerful new isotope with volatile and potentially dangerous qualities. A man named Nordstrom -- a feared international terrorist -- heads a small group of crooks who plan to intercept the isotope during its transport and layover in Chicago. Michael and K.I.T.T. are taken by surprise when out of nowhere, a juggernaut rams into them, completely destroying K.I.T.T., and appropriating the isotope.
