The Grand Tour: Dumb Fight at the O.K. Coral sees the tent travelling to Nashville. Jeremy Clarkson, Richard Hammond and James May introduce their attempt to save the world's coral reefs. In the interests of conservation, the three travel to Barbados and begin an earnest attempt to establish a new reef using only some car bodyshells as a foundation. Their efforts start badly and then get worse, involving inept crane driving, useless boat steering, and an embarrassing moment with a local hotel. Also in this show, Jeremy finally indulges his series-long Alfa Romeo obsession with a test of the new, 500 horsepower Giulia Quadrifoglio.
