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.
