Siblings 14-year-old Lily, 11-year-old Pattie and 7-year-old Ted Watts are evacuated from Manchester to the village of Oakworth in the West Riding of Yorkshire, where they are greeted by Bobbie Waterbury, her schoolmistress daughter Annie and her 13-year-old son Thomas.

Lily stops this idea immediately, and calls Thomas out on his ignorance of the realities of the world, revealing that their father was also killed in combat.
Thomas rallies Pattie, Ted and the rest of the local and evacuee children to create banners warning the train to stop, just as Bobbie and her siblings had done forty years earlier.
