Conspiracy (2015)

The first edition looks at unusual beliefs concerning the Nazis, including the idea that Adolf Hitler escaped death in 1945 and left the corpse of a double behind to fool the rest of the world. Plus, theories surrounding the whereabouts of gold looted by the Nazis and never seen again

The British Royal Family may have changed its name from Saxe-Coburg-Gotha to Windsor but some believe they didn't lose their allegiance to Germany. Was Edward VIII a Nazi sympathizer? Did his brother try to negotiate peace with Germany?

Reinhard Gehlen was the head of Nazi Germany's intelligence operation against the Soviets. That made him invaluable to the West during the Cold War, but did he simply tell his new allies what they wanted to hear, fueling the arms race?

The case of John Bingham, 7th Earl of Lucan, who disappeared in November 1974, coinciding with the murder of his children's nanny Sandra Rivett. Lucan was never caught or tried for the crime, but in the four decades since he fled numerous sightings have been reported of him from around the world. Some people believe he escaped justice, while others think he too was later murdered. Other cases considered include the kidnapping and murder of aviator Charles Lindbergh's baby son in 1927 and the disappearance of American union leader Jimmy Hoffa in an act some people claim was a mob-sanctioned hit

Tinsel Town has always been a place where bad things are covered up, including the gruesome murder of Elisabeth Short aka the Black Dahlia, and the deaths of both Bruce Lee and his son Brandon.

Did you know that alleged UFO sightings are as numerous in the UK as in the USA? This programme looks at three such cases from 1979 to the present day, including the only alien abduction actually investigated by the police, an incident regarded by many as the British Roswell, and claims that scientists at the European Space Agency are spending billions on making actual physical contact with extraterrestrials aboard a spacecraft with whom they have been communicating for the past 20 years.

Documentary series that puts the world's biggest conspiracy theories under the spotlight. Is it possible that a future pope turned a blind eye to Nazi war criminals escaping to South America after the war? Is there any truth in the theory that a Vatican insider poisoned Pope John Paul I? Was the KGB really behind the attempt to assassinate Pope John Paul II in May 1981? And was Roberto Calvi killed because he had helped the Mafia to launder money through the Vatican bank?

Perhaps the most famous assassination in modern times is that of President John F Kennedy. But there are those who claim that the murder of his brother Robert six years later was the next chapter of that chilling story. Although Bobby's assassin Sirhan Sirhan has spent almost 50 years in jail for the crime, Conspiracy reveals a theory which speculates that Sirhan was a pawn of the CIA - brainwashed like the character in 'The Manchurian Candidate'.

Bart Sibrel and journalist Marcus Allen claim to have evidence that proves that the American moon landings in the late 1960s and 70s were faked. Gary McKinnon, who hacked into the Pentagon computers in 2002, claims that he found information about a secret US space fleet in orbit and powered by alien technology.

There are claims that some governments have deliberately sacrificed their own people for political gain, including the landing of a British Airways passenger jet in Kuwait two hours after the Iraqi invasion of 1990, the Omagh bomb of August 1998, the attack on Pearl Harbor in 1941 and the 1951 outbreak of mass hallucinations in the small town of Pont-Saint-Esprit in southern France.

The Rolling Stones were jailed for drugs - was it a deliberate plot? The Sex Pistols never hit number one - were the charts rigged?

Did the Nazis burn down their own parliament so they could seize power in Germany? Did national governments conspire to hide who really bombed Pan Am flight 103 over Lockerbie? Was the U.S. Government behind the greatest and most horrific act of terrorism ever on American soil? And did the UK Government exploit a threat of a deadly poison attack in Britain, so it could justify going to war?
