The I.M.F. (Impossible Missions Force) is an elite group of Agents chosen for their various abilities to infiltrate foreign governments as well as criminal organizations that are seen as threats to the security of the nation. Originally, they were lead by Daniel Briggs (Steven Hill), but he was replaced by Jim Phelps (Peter Graves) after one year. Amongst its members are electronics executive Barney Collier (Greg Morris), actor and master of disguise Rollin Hand (Martin Landau), model Cinnamon Carter (Barbara Bain) and strongman Willy Armitage (Peter Lupus). In later years, Rollin leaves the team and is replaced by another master of disguise simply known as Paris (Leonard Nimoy), and Cinnamon is replaced first by young Dana Lambert (Lesley Ann Warren) and then Lisa Casey (Lynda Day George).
