French sibling Paul, Marie and Sophie are still working against the Nazis that are occupying their town, each in their own ways. Paul is a messenger who risks being out after curfew, Marie is "dating" a soldier in order to get information, and Sophie is unhappy to be so young that people don't think she can help-- until she finds a downed pilot carrying a critical message and is instrumental in saving him and helping get the message delivered. While they are struggling with missing their father as well as their neighbor, Henri, the Resistance is struggling with hos they should continue; whenever they sabotage the Nazis, the Nazis retaliate by killing randomly chosen civilians. Is the sabotage worth the cost of these lives, and will it bring the war to an end any sooner? The war does end eventually, and we are able to see what happens to the village and family afterwards. An author's note at the end gives more historical details.
