Mission: Impossible (1966) : 5x22

Alexander Vanin, arrested and convicted for espionage, hid a list of agents operating in the U.S. His control, Mishenko of the EEPR, has been ordered to get the list but Vanin refuses to give in because then Mishenko would cut him loose. The IMF must get the list. Vanin hypnotized himself to forget the list's location and only his wife Olga can give the trigger command to let him remember. Jim gets Olga to the U.S. while Barney and the others clear out the EEPR Consulate with a bomb ruse and then take it over and stage a party where the reunited couple meet (while Mishenko waits across the street for Barney to defuse the bomb). The IMF fake partygoers sneak out and Mishenko shows up to find Vanin there. To prove his loyalty and that he didn't talk, Vanin has his wife give the trigger, unaware that the IMF are listening in and get to the bus where Vanin hid the list before Mishenko can.
