The casualty department is kept busy treating five-year-old Jake , who has a rubber wedged firmly up his nose, and seven-year-old Steven , who has cut his foot while playing in a public fountain. Six-week-old Jessica is rushed in for an emergency operation because she cannot feed or breathe properly. Eight-year-old cancer patient Aaron is well enough to go home, once he starts eating properly again, but two-year-old Ellie , who has had surgery on a cancerous brain tumour, must return to hospital because of an infection.
