By April 1916, the fervor that accompanied war's outbreak has faded. In its place is a grim reality. Throughout Germany, essentials are rationed. Hope, too, is in short supply.

But during a visit from Dr. Stalling, the director of the Red Cross Ambulance Dogs Association, she witnesses a rare spark of optimism: as a German shepherd guides a battle-blinded soldier over a garden path, Dr. Stalling is inspired with an idea -- to train dogs as companions for sightless veterans.
