Premise:

Initially a special operative with the DXS (Department of External Services, a CIA type of organization), ever since the second season, MacGyver worked as a "troubleshooter" for Peter Thornton and the Phoenix Foundation. His missions ranged from environmental concerns (protecting endangered species) to international intrigue (rescuing U.S. agents from foreign governments). MacGyver refused to carry a gun and instead relied on his own ingenuity and the ability to find unique uses for seemingly ordinary objects.

Also of interest, stealing an idea from the James Bond movies, the producers involved MacGyver in a mini-adventure (or Opening Gambit) before the credits during a number of first season episodes.
