PREVIEW: Call The Midwife, BBC One

Change is on the horizon in Poplar. Sister Julienne (Jenny Agutter) must determine whether a private clinic venture that will generate much needed income for Nonnatus House is a suitable workplace for the Sisters, and enlists the help of Trixie (Helen George).

The plan causes great tension between Sister Julienne and Dr Turner (Stephen McGann) who is strongly against private health care. Their first falling out in over 20 years is felt by all, in particular Shelagh (Laura Main) who feels caught in the middle. Trixie, however, is thrilled to be challenged professionally and agrees to spend six weeks at the Lady Emily Clinic.

Lucille (Leonie Elliott) and Sister Frances (Ella Bruccoleri) are startled when a baby boy is born without legs below the knee. Sister Frances alerts Dr Turner, who frets this could be another Thalidomide case. Perturbed by the event, he determines to uncover the cause.

Meanwhile, with the Church’s financial support, Cyril (Zephryn Taite) moves into the flat above the Buckle’s paper shop, while Sister Monica Joan’s (Judy Parfitt) crisis of faith continues to weigh heavily on her mind.

Call The Midwife returns Sunday 18th April at 8pm on BBC One.
