The Secret Dealers are let loose in two ordinary homes to compete with each other for the best antiques and collectables they can find. Bidding with their own money against each other they go head-to-head with homeowners in an attempt to offer enough money to bag the goodies. Simon, David and Karen come face to face with budding antiques dealer Ian and his mum Margaret in the first house. Ian knows how to haggle and there are some serious battles for his precious items, including a delicious Minton dessert service and a highly desirable nineteenth century portrait of a lady and her dog. Simon is then joined by Mark and Christopher in retired ship’s captain Dimitri’s house, which is an Aladdin’s cave of treasures collected from all over the world. There are bidding wars left, right and center as canny Dimitri holds his ground, and the bids for a nine carat gold Gucci wristwatch go sky-high.
