This moving episode looks at the start and end of life, as well as the joys and fears of living alone. Seventy-five-year-old Graham is brought in to A&E having been the victim of a random attack - he's been stabbed in the neck with a pair of scissors by a stranger on his doorstep. Graham is also vulnerable because he suffers from schizophrenia. Meanwhile, 89-year-old Pat, a former nursery nurse, arrives having been found at the bottom of her stairs with no recollection of how she got there. Mum of five Cheryl has brought her four-year-old son Dylan into King's as he's struggling to breathe. Then things get even worse as Cheryl's eldest son Saner also has to be rushed in for treatment for a severe asthma attack.
