A sci-fi fan wants to sell his rare and valuable collection of toys to fund a dream holiday for his family. David spent a considerable amount of time in hospital as a child, born with a condition affecting his muscles and joints. He found escape from the world around him in sci-fi, and the joy his Star Wars figures and toys gave him as a child continued as he grew older, and he expanded the collection. Four decades on, David's mobility has become limited, and he's become dependent on his wife, Sarah. Now, he wants to repay his family's sacrifices by selling his beloved collection to fund a dream holiday. He knows his Colchester home has boxes of treasured collectibles, but he's uncertain of their financial value. Auctioneer Izzie Balmer has just one day to work her way through an intergalactic world of sci-fi as she trawls through David's specialist collection. She hopes a surprise find in the loft could lead to a shock at auction. Meanwhile, JJ Chalmers finds the right tools in the blue van to fix an old tricycle, and he makes a musical sewing table sing once again. Will there be an out-of-this-world reaction to David's collection at auction?
