Documentary telling the forgotten story of a heroic battle fought by the children of the British Memorial School to help liberate Europe from the Nazis. The school served a unique horticultural community of ex-First World War soldiers and their families living in Ypres in Belgium who lovingly tended the war graves. Steeped in ideals of patriotic service and sacrifice, many pupils and ex-pupils refused to surrender to the invading Nazi forces. Three surviving school pupils tell their extraordinary stories of resistance, illustrated with rare archive film.
