In this episode Jeremy Clarkson, Richard Hammond and James May attempt to show what would happen if The Grand Tour made a completely unscripted film with no pre-arranged locations, no set-up stunts, and no planned incidents. All they agree is that the starting point will be in Croatia, where Jeremy arrives in an Audi TT RS, Richard turns up with a not-at-all-comparable Ariel Nomad, and James brings along an old Lada which he has decided to turn into a fire engine. What follows is a demonstration of why some kind of script is generally a good thing. Also in this show, Richard takes the new McLaren 720S to the Eboladrome and in Celebrity Face Off Michael Ball goes head-to-head against Alfie Boe to find the world's fastest classical singer with an interesting connection to the British motor industry.

In this show, Jeremy Clarkson, Richard Hammond and James May set out to prove that old Jaguars are not only stylish and roguish, but also strong and reliable with a road trip across Colorado. Along the way they set laps around a punishing dirt track and test 0-100-0 performance at America's highest commercial airport before embarking on one of the most perilous challenges they've ever attempted; avoiding the expense of lift passes and ski equipment by going skiing in their cars. Also in this show, Celebrity Face Off finds the world's fastest actor whose middle name is George by pitting Luke Evans against Kiefer Sutherland.
