The Dragons are back and hungry to secure themselves the best deal. These are challenging times economically, but that hasn't deterred the nation's entrepreneurs from pitting their wits against the multimillionaire investors. In this series, a record number of entrepreneurs walk up the famous stairs to ask for an all-important cash injection that could transform their businesses and change their lives. The rival multimillionaires may be used to the odd glass of something sparkling, but Devon-based vineyard owner Geoff Bowen hopes his unusual business proposition will tempt them into investing. Inventor Derek Cozens thinks that road signs are so last century and wants to drag them into 2010 with his new product range. Do Dragons have a sweet tooth? One 24-year-old mum from Preston, Kirsty Henshaw, hopes they do and that it's the best way to get the cash she needs for her frozen pudding business. It wouldn't be Dragons' Den without a product getting tested to destruction, and calling a product 'safe' is like a red rag to a bull for one particular Dragon.
