Leonard Nimoy with a mustache doing espionage? Beam me up, 1969.
An Eastern Bloc nation is trying to develop a mind-controlling drug, a project led by Dr. Karl Turek. Phelps devises a plan to play Turek off against a rival, Colonel Borodin. Phelps and Meredyth pose as a pair of defecting U.S. scientists, who supposedly have developed an alternative drug to the one that Turek is working on. The IMF's scheme calls for Turek to try to kill Borodin, which will result in a trial where Turek will be discredited. But the complicated plan goes awry and the episode ends with Phelps under fire by guards.

Trivia, insights & behind the scenes
This was one of only two episodes directed by Paul Krasny, who later became a prolific TV director on shows like Charlie's Angels and Dynasty.
The 'mind-control drug' plot tapped into real 1960s fears of MKUltra and Soviet psychotronic warfare — pure Cold War paranoia fuel.
