The citizens of Spokane, a small town in Washington state, awaken to the sight of North Korean paratroopers dropping from the sky. The U.S.A. has been invaded and their hometown is the initial target. Without warning, the town is unable to fight back and finds itself under enemy occupation. Evading capture, a group of young patriots - led by Jed Eckert (Hemsworth) seek refuge in the surrounding woods, training and reorganising themselves to become a guerrilla group of fighters. Taking inspiration from their high school mascot, they call themselves the Wolverines, banding together to protect one another, liberate their town from its captors and take back their freedom.
