First transmitted in 1978, this 25th anniversary edition of Panorama with Tom Mangold continues with a report on space weaponry, directive energy weapons, particle beam weapons and high energy lasers.

Michael Cockerell's report brings all the new facts together for the first time. It includes TV interviews never before seen with the President's alleged assassin, Lee Harvey Oswald, and his killer, Jack Ruby. It examines whether the recently uncovered plots between the CIA and the Mafia to assassinate Fidel Castro backfired and led to the death of President Kennedy-as his brother Bobby feared. Producer Anthony Summers work on this film led to his seminal 1980 book 'Conspiracy'.
