Overview: The Den is down a Dragon as Hilary Devey is temporarily absent, however while only four multimillionaire investors preside over proceedings, they are as keen as ever to find the next big thing to back with their hard-earned cash. In this episode recorded before his own heart scare, Duncan Bannatyne and his rival Dragons get to see how a doctor, a nurse and a paramedic would treat a cardiac arrest in the Den. Plus a nervous Aldershot butcher seeks investment in his award-winning sausages, and a father and daughter team from Hertfordshire showcase their troop of drummers. Also in the Den, a first time inventor advises how to keep dry while cleaning your car wheels, a former teacher asks the Dragons to make origami puppets, and an inanimate object speaks for itself and asks for £50,000.
