The year is 1914 and Pips Maitland resists her mother's wishes that she settle down with a suitable husband and raise children. All she wants is to be a doctor like her father and her brother, Robert. Hearing that her father's friend, Dr John Hazelwood, is forming a flying ambulance corps to take to the Front, Pips is determined to become one of its nurses. She asks her lady's maid, Alice Dawson to accompany her along with Robert and fellow doctor Giles Kendall. Nothing could have prepared them for the horror there. But even amidst the shelling and gunfire, love and friendships blossom - just like the poppies on the Flanders fields.
