On May 10th, 1940, Nazi Germany attacked France, Belgium, the Netherlands, and Luxembourg. Their advance was swift, and led to the fall of France just six weeks later. In the fictional French village of Pontain-L'Écluse, 13-year-old François is shocked to see his fellow villagers—and even some of his family members—accept this occupation and submit to the laws and behavior of the German invaders.

Determined to thwart the enemy, he enlists his friend Eusèbe to help sabotage the Nazis and motivate his village to unite against them. A fascinating tale of the Resistance and of actions taken by its youngest activitsts, inspired by true stories.
