Movies like Probe (1972)

That hipster ring that 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. This 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. In this pilot film for the short-lived series "Search," Lockwood is on a quest to recover priceless diamonds stolen by the Nazis during World War II.
