Get Smart (1965)

S5E1 Pheasant Under Glass

Assigned by CONTROL to save Professor Milo Pheasant, Max and 99 discover he is trapped inside an unbreakable glass dome. Kidnapped by KAOS, the professor is held in a nuclear-glass cube. When Max and 99 attempt a rescue at KAOS headquarters, they are unable to penetrate the dome and must retreat. During their escape, 99 shares the news of her pregnancy, which causes Max to inadvertently reveal his secret identity to a journalist. This blunder jeopardizes their mission, as CONTROL's plan hinges on singer Rosa LaCosta, who can shatter glass with her voice. To salvage his role, Max consults Dr. Proctor, who has a method for disguises. After experimenting with various faces, Max selects one to successfully infiltrate KAOS and rescue the professor.
