In March 1944, the world was in turmoil during World War II, while at the same time, children in a small rural corner of France began a "war". For a long time, children in Longwei and Weiheng, two neighboring villages, clashed with each other, but this time, they came up with a new idea for the "war"-the children decided to compete with each other for buttons, shoelaces, belts and so on. Whoever can humiliate each other naked first wins. They named the war "the War of buttons". The "button war" is just a game of children, and it doesn't matter who wins or loses. At this time, a Jewish girl, Violette, came to the village. She moved Lebrac, the "king of children" in Longway, but where did the girl come from? What kind of story is hidden behind her?
