A water shortage means that the Maternity Home is busier than ever. Two old school friends, Shirley and Marion, are reunited. Both are pregnant with their first child, but are now worlds apart. Marion shuns Shirley’s attempts at renewing their friendship and they part ways, but are brought together later in the most unexpected way…

Elsewhere, Barbara makes a revolutionary suggestion to help Sister Mary Cynthia’s bedsore patient, Tommy Mills. However, it is discovered that it is his steadfast wife, Gert (played by Una Stubbs), who is the one most in need of care.

The love between Tommy and Gert makes Fred think about taking the next step in his relationship with Violet.
