The tranquil town of Greylock, N.H. is upended when a massive vein of a valuable mineral is discovered underneath it. When a mining company moves in with plans to extract the mineral, it threatens to wipe Greylock off the map.
With the townspeople in danger of losing their homes and livelihood, high school teacher Sarah Cooper steps up and proposes that Greylock declares independence. This would allow it to gain international sovereignty and protect its land for good.
After a federal judge agrees that Greylock isn't part of the United States, the town becomes a new nation. Now, Sarah and her allies have the daunting job of building a country from scratch.
