In the dark days of war a new hope is born... 1939. Mary Vale, a grand and imposing Mother & Baby Home, sits on the edge of the Lake District. Its doors are open to unmarried women who come to hide their condition and find sanctuary. Women from all walks of life pass through Mary Vale, from beautiful waitress Emily, whose boyfriend has vanished without trace, to young Isla, cast out by her wealthy family after her first year at university goes horribly wrong. Awaiting them is Nurse Ada and Sister Anne who work tirelessly to aid the mothers and safely deliver the babies. But the unforgiving Matron and Head of Governors, Captain Percival, have other, more sinister, ideas. As war looms the women at Mary Vale must pull together for the sake of themselves and their babies and Ada and Anne must help protect their patients, no matter what the cost.
