Auctioneer Catherine Southon, market trader Gary Barton and upholsterer extraordinaire Micaela Sharp head to Lewes for a day to scour its many antique shops, scrap yards and flea markets. Once the day is done, they have just three weeks to turn their goodies into gold. Will any of Catherine's clients be interested in her stethoscope? Will the punters at Gary's market in Glasgow's famous Barras want to shell out £1,000 for his vintage mobile phone? And will Micaela be able to upholster so many bits of furniture in time to put them up for sale?
