Attack on Terror: The FBI Versus the Ku Klux Klan is a fact-based, two-part TV movie. The film is a dramatization of the murders of three civil rights workers in Mississippi in 1964. The FBI, personified herein by southern operative Wayne Rogers, is brought in to investigate the trio's disappearance. Upon the discovery of the bodies on August 2, 1964, the feds follow a trail of (admittedly skimpy) evidence which leads to the local chapter of the Ku Klux Klan, headed by the virulent Glen Tuttle (Rip Torn). The first part of Attack on Terror was originally telecast February 20, 1975. The film was based on the book by Don Whitehead.
