This story is not a work of science fiction. Everything you’re about to hear is true.


On 26th November 1977, a mysterious alien voice calling themself “Vrillon,” broke onto the Five O’Clock News.


Vrillon had a simple warning for the viewers of Southern Television: live in peace or leave the galaxy.


For forty-five years, those responsible have not been identified. Tommie Trelawny has reopened the case.


Who, or what, was ...

For Southern Television, a TV station based in the south of England, November 26th 1977 was a day like any other.


Until 5:00pm, when this happened.


“This is the voice of Vrillon. Representative of the Ashtar Galactic Command speaking to you.”  


Nobody came forward to claim responsibility for this event. No one has been caught. For forty-five years, this strange incident has remained a mystery.


For Stak, Tommie...

As The Interruption took place over the airwaves, we don’t have any physical evidence left behind. But we do have one thing: the message. 


You see, at the time no one really listened to what the alien had to say, it was simply shrugged off. But Tommie thinks that was a mistake…

Many UFO movements believe aliens can take control of humans and use them as their mouthpieces.


Many of these “contactees” are still around today and some offer their psychic services online.


It gave us an idea: why not put our questions to Vrillon directly?

In the last episode, we met two amateur investigators, StarDoG and AP Strange.


Like Tommie, the duo had fallen down the Interruption rabbit hole and had been working on this incident for years – with limited success.


However, something they say sends Tommie on a road trip… and somehow he ends up on the phone to a certain spoon-bending psychic.

We have explored the motive, but what about the method?


Tommie hears from some of England’s most well-known pirate broadcasters.


These pirate radio DJs weren’t messing around, they took their craft seriously, they loved what they did and they were willing to take risks.


A new two-pronged search begins to unfold… Operation Space Pirates.

Out of a converted shop front in Fulham’s High Street lies the Aetherius Society – Britain’s oldest UFO religion.


A large, life-like painting of George King, the founder and prophet, hangs above the Executive Secretary’s desk.


In 1959, George King appeared on the BBC’s Lifeline, where the Cosmic Masters appeared to speak through him.


The message was strikingly similar to that of Vrillon’s...

Two days after a massive dead end in their investigation, Tommie sends his producer a voice note: “That man is Vrillon, that man is Vrillon…”


And with those words, the 45-year-old case has been solved.


But, who was behind it?


Well, you’ve actually heard from him already…

Forty-five years later, Tommie has gone on a journey through UFO Religions, talking to alien impersonators, psychic illusionists and travelling to alien churches.


He’s found out who was behind The Interruption, but the story doesn’t finish there.


Why did he do it? Why did a former radio pirate turn gadget guru hijack a television broadcast?


The answer begins on a park bench at the University of Bedfordshire.
