It's April 1970 and Trixie oversees the care of Arlene, an unmarried mother who is heavily pregnant and under the care of the district midwives. Rising rates of gonorrhoea in the district cause alarm when Zeta, a young Cypriot expectant mother, is diagnosed. She is utterly distressed and bewildered by her diagnosis and her husband Mehmet denies any extramarital affair. Meanwhile, Cyril and Rosalind volunteer together at the homeless shelter.
