Investigative author Jim Bamford probes the untold story of the elite corps of clandestine astronauts who were never told of the true purpose of their training program. Bamford will travel to Russia to reveal the secrets of the Soviet response -- the prototypes of the "Almaz" military space stations that, if deployed, might have led to a Cold War showdown in outer space.
