As the Summer of Love faded to the winter of our national discontent in the fall of 1968, Inspector Erskine (Efrem Zimbalist, Jr..), Special Agent Colby (William Reynolds), and Assistant Director Ward (Philip Abbott) continue to battle the nation's enemies, foreign and domestic. Delivering drama at the height of it's powers, the FBI's well-oiled machine of TV talent continued to draw in the star power - both the iconic and the up-and-coming, from golden age great Ralph Bellamy (as a Nazi sympathizer!) to soon-to-be TV superstar Chad Everett (as a psycho wannabe Vietnam War hero). Other faces found among the cases of extortion, espionage, kidnapping and killing include Dawn Wells, Susan Strasberg, Dorothy Provine, Cicely Tyson, Lynda Day and Gene Tierney as well as Dean Stockwell, Robert Duvall, Harrison Ford, James Caan, and a young teen Ronny Howard.
