Premiere episode, later released as a TV and theatrical movie entitled To Trap A Spy.
The New York headquarters for The United Network Command for Law and Enforcement (U.N.C.L.E.) is compromised by a team of assassins from U.N.C.L.E.'s arch enemy, THRUSH, in an apparent preemptive stick before attempting to overthrow a new country's leadership.
The pilot and then later movie version would have re-named characters, added or deleted scenes and changes in the plot from this television episode.
Solo and Kuryakin investigate a Scottish town where everyone has mysteriously died of old age in a matter of hours. Their findings lead Solo to Norway in search of the source of the chemical causing the premature ageing. While waiting in the airport in London for his flight to Norway, Solo meets Christopher Larson (played by 13-year-old Kurt Russell) who fancies Solo as a new husband for his widowed mother back in New York. Larson becomes attached to Solo and follows him to Norway, where the two of them combat the evil General Yokura (Strong), who is behind the plot to develop the ageing chemical.
A mysterious fungus is devastating Russian wheat fields, and all the evidence points to the fungus being developed in the USA and sent to Russia in missiles. When Solo investigates along the California coast, he encounters the madman (Jones) who has masterminded the plot in an attempt to start World War III by capturing the scientist who developed the fungus and forcing him to work with him. With the help of the scientist's daughter (Kristen), Solo must try to stop the missiles before Russia retaliates.
When the leader of an eastern European country is assassinated, Solo stages a raid on the lying-in-state ceremony and steals a dove-shaped medal from the leader's body. The medal contains a list of THRUSH agents engraved on it. In attempting to escape from the country with the medal, Solo must contend with the country's master spy, Satine (Montalban), but receives some unexpected help from an American teacher (Lockhart) and her class that are on a school visit to the country.
