When the United States falls to foreign invasion, millions of Americans become refugees in their own country. But resistance is rising from an unexpected place. Broadcasting from a refugee camp on the Canadian border, DJ Mose B sends out coded messages in the beats and scratches of hip-hop music over a station known as Radio Free Amerika.

As young rebels decode the signal, what begins as music becomes a movement, transforming ordinary citizens into freedom fighters. Soon unlikely heroes emerge as those left behind rise up to save these United States and claim their God-given right to life, liberty, and the pursuit of happiness.
