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.
