That hipster ring special agent Hugh Lockwood wears? It's a camera, transmitting image and sound of his surroundings. It's also a scanner, detecting telltale changes in pulse or other biometric readings of himself and the people around him. The ring and more electronic devices - some embedded - keep Lockwood linked with Probe Control, where experts and banks of computers provide instant mission-critical warnings, intel, even language translations. Hugh O'Brian portrays Lockwood and Burgess Meredith is his mission director in Probe, a telefilm that has Lockwood on a quest to recover priceless diamonds lost since World War II. O'Brian and Meredith reprised their roles in 'Search', the 1972-73 TV series inspired by the film.
