After a launch full of twists and turns, Rob Brydon's intrepid players continue this adventurous game as they head towards their next Destination X. They're crossing a border and reaching new heights in a series of nerve-racking and heart-stopping challenges, ranging from a majestic beach to one of the most iconic peaks in Europe.

But the trip to the coast is no picnic as Rob poses the players a moral dilemma that really pushes their buttons. Who will give in to temptation to get themselves one step closer to £100,000?

After the back-stabbing challenge, the passengers brave an action-packed escape room in the sky, leading one team to a potentially map-beating advantage. But who can trust who on the bus, and have the players seen enough to figure out where in the world they really are? Will the players decide to share information, or will they send each other in the wrong direction? It's finally dawning on the passengers that this can be a brutal game.

After not one but two shock exits, and some new faces on board, the X-bus crosses yet another border and makes its way to a country famed for music and rolling hills. The new passengers are dumped in at the deep end as host Rob Brydon arranges for everyone to spend a night in a spooky castle. It's a race through the rooms to gather clues and make it to the room with a view to finally see where they actually are. Another challenge high on a hill tests the passengers' memories, and the bus seems even more divided than ever, with the original players closing ranks against their new bus mates.
