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 with 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.
