The Sisters and the midwives have moved into a new building and have welcomed a new colleague, Sister Winifred. They have considerably more space and Dr. Turner manages to find a hall where they will be able to hold clinics two afternoons per week. After few of their patients come to the clinic, Chummy takes a bold step. Not only does she create a number of recreational activities she writes to Princess Margaret asking for an official visit, which she accepts. Meanwhile, Jenny is helping Merle and Billy Vickers. Merle had given birth only a few months ago but the newborn is always sick and his older brother is often ill. Jenny and Dr. Turner conduct a number of tests but they are all inconclusive. As it drags on, the Merle loses all confidence in her abilities as a mother. Sister Monica Joan thinks she knows what is wrong and puts them on the right track.
