It is late summer in East Sussex, 1914. Amidst the season’s splendour, fiercely independent Beatrice Nash arrives in the coastal town of Rye to fill a teaching position at the local grammar school. There she is taken under the wing of formidable matriarch Agatha Kent, who, along with her charming nephews, tries her best to welcome Beatrice to a place that remains stubbornly resistant to the idea of female teachers. But just as Beatrice comes alive to the beauty of the Sussex landscape, and the colourful characters that populate Rye, the perfect summer is about to end. For the unimaginable is coming – and soon the limits of progress, and the old ways, will be tested as this small town goes to war.
