As punishment for some youthful high jinks, 16-year-old Jimmy Frazier is made to volunteer in a London hospital. The experience shocks him, and he swears he will never set foot on a ward again. Two decades later, older but not a lot wiser, some strange twists of fate lead Jimmy back to hospital - but this time as a student nurse. Along with a motley crew of fellow students, Jimmy throws himself into the heart of the NHS. Whether caring for patients in children's hospitals, prisons, mental health facilities or post-surgical wards, Jimmy and his fellow students attempt to make a difference. On their way they are inspired by the angelic Super Nurse and the acid-tongued Mr Temple. But can they stick out the three years it takes to make the grade as a fully-qualified nurse...?
