The head of the "Impossible Missions Force", a top-secret government group of operatives, starts a tape recorder and finds out about his latest assignment. Throughout most of the series, they would have to stop some petty dictator or powerful bad guy from whatever evil plot they had against the U.S. or Democracy in general. The elaborate use of electronic gadgetry, masters of disguise and detailed plans that require split-second timing made this tv show an "on the edge of your seater"!
