One bright spring morning in the woods of France, a soldier, blinded by
the war, is found by a little girl named Coco, and her older sister
Marcelle. In return for their kindness, the soldier tells the sisters
marvellous tales, each story connected to the keepsake he carries in his
pocket: a perfect, tiny silver donkey. As the days pass and they
struggle in secret to help the soldier reach home, Coco and Marcelle
learn the truth behind the silver donkey, and what the precious object
means: honesty, loyalty, and courage.
