In an exhilarating four-part series, four celebrity duos put their driving skills and relationships to the test as they join in on a part of the Endurance Rally Association's Road to Saigon in a fleet of classic cars. Each of the celebrity duos sport a range of skills and start their adventure in bespoke rally-prepped cars: broadcasting legend Noel Edmonds and his wife Liz drive a classic MGB GT, husband and wife Martin Kemp (Spandau Ballet) and Shirlie Kemp (Wham!) drive a 1972 Mini, restaurateur and food broadcaster Andi Oliver and her TV presenter daughter Miquita Oliver have the oldest car - a 1959 Morris Minor, and friends Tinchy Stryder and Jordan Stephens (Rizzle Kicks) have been given a Hillman Imp.

From Chiang Mai in northern Thailand through Cambodia and Vietnam, their challenge is to drive over 3,000km, through some of the least-explored areas of the region and taking on some of most challenging roads in the world. Over 12 days, the series captures all the laughs, beautiful landscapes and inevitable drama of this truly unique journey revealing if the celebrity ralliers have got what it takes to make it all the way to the finish line. To be in with a chance of getting to the finishing line, they have to work closely in their driver/navigator pairs finding their way using a Tulip Map and try to keep their cool when engines fail and cars break down. The ralliers also have a chance to soak up the sights and sounds of this part of the world and reflect on its recent past.

In the first episode, the celebrity pairs are plunged straight into the busy rush hour of northern Thailand's biggest city, Chiang Mai, with only an obscure Tulip Map to guide them onto the open roads and up over the phenomenally steep Chae Son Hills. This once-in-a-lifetime experience tests the teams, and their cars, to the limit. Tinchy Stryder and Jordan Stephens have absolutely no experience of classic cars. Andi and Miquita Oliver are on this trip to bring them even closer as mother and daughter, but tensions soon rise as Andi is forced to take on all the driving. Shirlie and Martin have been married for almost 30 years but the car is the only place where they argue, and things take a turn for the worse after the second day's speed test. Noel and Liz experience the spiritual east in a Buddhist temple and by the third day are going out of their way to raise the other team's spirits. Show less
