Holby City stars Rosie Marcel and Bob Barrett - aka Jak Naylor and Sacha Levy - swap scalpels and scrubs for curios and collectibles in a very competitive Road Trip. They scour the Cambridgeshire and Bedfordshire flatlands for antique bargains to sell at auction in St Ives, near Huntingdon. Rosie pairs with expert David Harper, and Bob with auctioneer Louise Gostelow. Bob’s Road Trip is thrown into crisis when a flooded river blocks his way to the antique shops. However, on a circuitous detour he fulfils a 50-year wish to get his hands dirty learning about landscape gardening at a location close to his heart. Meanwhile, Rosie swaps her classic car for another vehicle once driven by royalty, as she explores the historic collection of planes and sports cars left by a man passionate about speed. Best friends at the start of their Road Trip, but will it be Rosie or Bob with the bragging rights at the end?
