Antiques experts Izzie Balmer and Tim Medhurst set off on a road trip around north Wales. Searching for treasures and relics from a bygone age, they compete to make the most money at auction. Izzie gets in a spin about a mid-century swivel chair, and Tim’s inner child comes alive when he discovers three toy cars. But it’s not all shopping as Izzie learns about the Menai suspension bridge, a wonder of the engineering world, while Tim takes a trip on the world’s oldest narrow-gauge railway. Their trip ends at auction, where their antiques go under the hammer and they find out who has made the most money.
