Call the Midwife

PBS | 9:00 pm

This year's edition of this historical drama's traditional holiday episode opens in 1966, as Lucille and Cyril (Leonie Elliott, Zephryn Taitte) prepare for their winter wedding. Meanwhile, the Nonnatus House team faces its busiest Christmas Day ever, as expectant mothers — each with her own challenging issues — fill the maternity home. Fortunately, Mother Mildred (Miriam Margolyes) is present to lend her support. Stephen McGann, Helen George and Jenny Agutter also star.
