Following on from `Helicopter Heroes', `Helicopter ER' is a series capturing the rescue work of the Yorkshire Air Ambulance. A film crew follows the team of medics as they attend to patients in life or death situations. Stretching over thousands of square miles, the dales have beautiful but treacherous landscapes, where those needing medical assistance can find themselves in life-threatening conditions. Over the series these real-life heroes are seen performing surgery in the street, bringing back a patient from a cardiac arrest and dispensing painkillers to those in a lorry crash.
