Malcolm and Violet scramble to pack their things and rush to the embassy with their dad. There is an evacuation plan to get Americans and their allies out of the country―as long as your name is on the official list. The twins and their dad are on the list, but the siblings realize their best friend Bao isn’t.

​​​​​​​Determined to help Bao and his family, Malcolm and Violet sneak out of the embassy to find their friend and convince officials to put his family on the list. But the streets have become a battleground, and Malcolm and Violet don't have much time. If they don't make it back to the embassy before the last helicopter leaves, they'll be trapped behind enemy lines forever.
