"The Commissioner" sent US special agent Steve Mitchell to exotic locales all over the world, where he would encounter adventure and international intrigue in pursuit of some secret. Each show would always open with a brief teaser scene from the episode to follow. After the intro, Steve Mitchell would be summoned to the office of 'The Commissioner', the regional head of an un-named US State Department agency created to address international unrest as it affected U.S. interests. "The Commissioner" would give background information, explain the current situation and tell Steve his assignment. Steve's cover identity, in almost all his adventures, was that of a suave debonair foreign correspondent for an unnamed print publication — his assignments invariably involved deceit, trickery, and violence, all tied together into a successful resolution by the end of the episode.
