One morning in the woods of France, a blinded soldier, is found by two sisters, Coco and Marcelle.

In return for their kindness the soldier tells the sisters marvellous tales, connected to the keepsake he carries in his pocket: a tiny, silver donkey.

As the days pass and they struggle to help the soldier reach home, the sisters learn the truth behind the silver donkey and what the precious object means: honesty, loyalty and courage.
