Mission: Impossible (1966) - 7x07 - Underground- Followmy.tv

Gunther Schell, the brains behind many Syndicate operations, escaped with the aid of a gang specializing in smuggling criminals out of the country - the IMF must locate Schell and the millions in Syndicate money he hid. The gang apparently brainwashes their "clients" and steals their money. Jim goes in as a doctor wanted for murder with his cash hidden after Barney hypnotically programs him only to divulge the information they want. Jim is contacted by the gang, led by Clavering, but the IMF loses contact with him when he's moved in a lead-lined casket to the gang's location, where Schell (who hasn't broke yet) is also at. Jim manages to knock Schell into a coma by triggering his diabetes and claims only he can save him. Jim calls in Willy as an anesthelogist and then the two of them knock out the gang and get Schell out. Barney sell's Schell's location to his superior, Lutz, and they all go to the hidden cash, where the police take them into custody.
