Synopsis by Hal Erickson
General Zek (Titos Vandis) conspires with munitions manufacturer Ismir Najiid (Sandor Szabo) to kill Middle Eastern potentate King Said (Joe E. Tata) with a truckload of nitroglycerin. The conspirators then plan to place the blame for the assassination on a neighboring country, thereby sparking a war that will enable Zek to assume command of both nations. To preserve the balance of power, the IMF must steal the highly volatile nitro, save the King, and discredit Zek. Mark Lenard, best known as Spock's father on Star Trek, makes his second Mission: Impossible appearance as Aristo Skora. Originally telecast on March 23, 1969, "Nitro" was written by Laurence Heath.
