Antiques experts travel across the country, competing to make a profit at auction. Catherine Southon and Philip Serrell battle it out for the last time. Travelling through south Wales, the old Citroen DS20 takes them to the final auction in Wells, Somerset. Catherine heads to the Royal Mint and finds out how Sir Isaac Newton revolutionised coins to prevent forgers making a fortune. Phil breaks from shopping for a little lesson in culture at the Bristol Old Vic and discovers why it is a miracle the building still stands today. At the final auction it is the battle of the watches. Phil and Catherine each buy fascinating timekeepers, but which one will make the most profit?

The second instalment of this road trip adventure with Paul Laidlaw and Claire Rawle begins in the city of Sunderland. Claire finds out about the Tynemouth Volunteer Life Brigade and military-mad Paul goes giddy when he visits a military observation post in Blyth.

The competition is well and truly on. Paul finds some RAF stereoscopic aerial reconnaissance photographs of German U-boats at a great price, but will they make the big profit he needs to clinch victory from new girl Claire when they go to auction at East Boldon, Tyne and Wear?
