The bucolic tranquility of Greylock, N.H., is upended when a massive vein of coltan, an incredibly valuable mineral used in tech, is discovered under the town. Lydon Industries swoops in with plans to extract the mineral and wipe Greylock off the map. With her friends and family in danger of losing their homes, rebellious high school teacher Sarah Cooper vows to stop Lydon's bulldozers. Sarah enlists her friends in the fight, but there seems to be no way to stop the town's impending demise -- until Sarah proposes an oddly intriguing solution: Greylock could declare independence. If Sarah and her friends can convince the town to vote for independence, Greylock would gain international sovereignty and could protect its land for good. After a federal judge agrees that Greylock isn't -- and never was -- part of the United States, the town becomes a new nation. Now, Sarah and her allies must confront an even more daunting task and build a country from scratch.
