In order to confront their theories, Andrew Maxwell takes four conspiracy believers on a road trip from Leeds to London to recreate the exact journey the 7/7 bombers took.

It has been seven years since the London bombings of 7/7, one of the worst terrorist atrocities in recent British history. Unbelievably, some people question the official version of events and think the British establishment orchestrated its own 9/11-style attacks in order to firm up support for the war in Iraq.

Comedian Andrew Maxwell thinks this is nonsense and, in an effort to tackle the truth, is taking four such conspiracy believers on a road trip from Leeds to London to recreate the exact journey the bombers took. Each of them believes a different conspiracy theory - from claiming the train times were falsified by the government to the idea that home-made bombs could never have caused such damage. They talk to eyewitnesses, families of victims, government officials and specialists to uncover the truth about what happened that day.
