Rob Brydon takes 13 strangers on the adventure of a lifetime - but can they figure out where in the world they are?

The mystery tour reaches new heights, and tensions are high, as the passengers look for clues to the location of Destination X.

The European bus trip goes off-road and off the rails as the players find themselves in another mystery country. This time, host Rob Brydon has even more tricks up his sleeve.

A night in a spooky castle has the passengers on edge, and loyalties are tested when it comes to sharing clues to Destination X.

The X-bus now makes its way to one of Europe’s biggest winemaking regions and the halfway point on this extraordinary journey, and host Rob Brydon still has plenty of tricks up his sleeve.

For the first time, host Rob Brydon reveals to everyone on the X-bus where in the world they actually are. And the players’ game plans are revealed - who has been keeping secrets from whom?

Tensions mount as the passengers are given the opportunity to scupper each other in a challenge that will test their memory and their reflexes, as well as their loyalty to each other.

After a shock elimination, the X-bus continues its journey towards the £100,000 prize with just five players remaining. Two alliances have formed and plans are being hatched, but can they play nice?

With just four passengers left on board, the X-bus travels further into Europe and one step closer to that £100,000 prize. Which of the semi-finalists will fall at the last hurdle?
