Now dating surveyor Alec, Jenny joins the other midwives in their superior new base, along with latest recruit, Sister Winifred. Jenny is concerned for Merle and Billy, a young couple whose infant boys are permanently ill, causing them to doubt their parenting skills, whilst added is stress provided by the fact that Billy's brother died as a toddler. Surprisingly, Sister Monica Joan accidentally provides Dr. Turner with the solution to the children's complaints, thus saving them. Chummy, meanwhile, drums up support for the newly opened, but under-used ante-natal clinic, taking advantage of a royal visit to put it in the spotlight. The day is a success, and to add to it, Chummy helps an older woman with a difficult birth, resulting in Sister Julienne asking her to return to work.
