The NHS is facing a perfect storm, caught between huge increases in demand and the prospect of a massive £30 billion deficit. Without revolutionary change the NHS as we know it will become unsustainable. Filmed over six months in Liverpool, this Panorama special reports from the frontline of the battle to transform the NHS. It tells the moving stories of patients living in one of the unhealthiest areas in Britain, whose 'long-term' and 'lifestyle' conditions threaten to overwhelm the NHS. And also of the healthcare professionals trying to save them whilst at the same time fighting to fundamentally change the way their organisation works.
