A GIS movie par excellence, much of the story is told through animated low elevation mapping of the fields, battlegrounds, and trenches of world war I. This movie looks at the experiences of Siegfried Sassoon, Robert Graves, and JRR Tolkien, and the way the war shaped their words and their spaces and came to haunt their lives later on.
French villages, shown on old photographs stitched together to give complete landscapes, tagged with 3D pointer-labels, look old and sepia-toned. They look bleak, ashy, barren; then we suddenly see layered on top what the place looks like today: bright, green, sunny, a far cry from century ago.
