Time to give away your age! Who remembers a spy show from the 70s called "Search?"
It had three leading men who rotated each episode. They worked for an organization called "World securities."

They were like James Bond & had all this cool gadgetry like micro cameras that could be worn like a ring, or a tie clip. Also an implant in their neck near the ear where "Probe control" could talk to them, but no one around them could hear.

I've tried to find that show on DVD, but no luck, so far! :frown:
