His sweetheart, 15-year-old Charlotte, stays behind to earn her nursing certificate, along with John Malcolms twin sister, Maggie, who recognizes the opportunity to create a new life for herself. Charlottes brother, Francis, sees only tragedy in the war, but feels the pressure to join up. And Alex, below the recruiting age, is determined to reach the front lines somehow.
