Mission: Impossible (1966) : 3x9

Milos Kuro, minister of culture has been using propaganda to discredit his premier, Leon Vados. Vados is a progressive trying to negotiate a nonagression pact with the U.S. When in the U.S. Kuro witnesses a play written by Cinnamon that undermines Vados and the U.S. He arranges to have it staged in his country. But Cinnamon and Rollin leak the play's existence to Vados. Vados attends a rehersal and is seated beneath a special radar disk that creates a sound envelope so that Vados hears only the special dialogue the IMF has created that makes Vados out to look like a fool. Vados has Kuro arrested.
