Dom Joly sets off on his travels again, immersing himself in the strange world of conspiracies. On his journeys he meets conspiracy theorists galore in destinations all over the world, some famous, some rather less so. Conspiracy theories used to be fun, a bit of laugh.

Did we really land on the moon? Was Paul McCartney cloned? Nowadays, however, in the aftermath of Donald Trump, a global pandemic and the ever-increasing influence of social media algorithms, they are part of the body politic and a massive cause of division and mistrust. In The Conspiracy Tourist Dom Joly sets out on a global journey to find out what's going on. His travels see him meeting followers of QAnon, hunting for UFOs in Roswell, chasing Alex Jones of Info Wars around Austin, trying to prove that Finland exists and taking a flat-earther to the edge of the world.

On the way Dom inevitably finds the funny and the quirky, but he also tries to understand what makes people so drawn to conspiracy theories. What if those he has long dismissed as crazed loonies actually have a point? What if we are the sheeple and they've been right all along? Join a wide-eyed, slightly jaded, adventurous tourist on a very different kind of sight-seeing trip.
