Regulators infiltrate the borderlands to stamp out the rebels. As Lena navigates the increasingly dangerous terrain of the Wilds, her best friend, Hana, lives a safe, loveless life in Portland as the fiancée of the young mayor. They live side by side in a world that divides them until, at last, their stories converge.
