Nurse Millie Sullivan is now Nurse Millie Smith, having married aspiring MP Jim Smith. The war has ended and the NHS has just come into action, so the nurses are busier than ever as the community realise that they no longer have to pay for the services. Minor ailments need attention, babies need to be helped into the world and some of the larger-than-life characters need keeping in line so Millie has enough drama to deal with without having to deal with more from home...and Alex Nolan, her ex-fiance, is back in town.
