The teams have the finishing line in their sights as they travel along Vietnam's coastline to the closing ceremony in Saigon. Noel and Liz fear they may have pushed their car too far over the past 2,500 kilometres, Andi struggles to cope with long hours behind the wheel, and Tinchy and Jordan switch to driving a Soviet era jeep. The last day of the journey brings one duo to the brink of disaster. Last in the series.
