Mission Impossible: The top-secret assignments taken on by this elite group of agents usually involved disrupting the activities of various small foreign powers seeking to create problems for America or the Free World. By the last season the agents began to run out of little Communist countries and obscure principalities, so they concentrated their efforts more on dealing with organized crime within the U.S. All the plans executed by the I.M.F. were incredibly complex and depended on split-second timing and an astounding array of sophisticated electronic gadgetry. The leader of the group, Daniel Briggs during the first season and Jim Phelps is subsequent seasons, devised the complex plans used to accomplish the teams missions. Barney Collier was the electronics expert and Willie Armitage provided the muscle. Rollin Hand was an expert at disguise and Cinnamon Carter was the versatile, beautiful female member of the team.
