Antiques experts travel across the country, competing to make a profit at auction. The tartan twosome, Paul Laidlaw and Natasha Raskin, are antiquing in Norfolk, but somehow finding time to go down a Neolithic flint mine and go into print. It's the final 'Round Britain Rummage' and they unearth a rarely seen art nouveau food warmer and a charming 19th-century table croquet set. They're headed for one last auction in Diss and it's still anyone's game. Who will win this Road Trip?
