It's twelve years before Captain Leo Davidson of the space station Oberon crash-landed on the planet of the apes. Border patrols are growing more aggressive, with hundreds of humans from the tribes near Ape City being taken captive. Despite this, Daena's mother, Sarai, is determined to reach a truce. Realizing this can only happen if humans and apes stand on equal footing, she resolves to free the human slaves to work on building a human city to rival the brilliance of Ape City. Sarai already has one powerful ape ally, Ari, but will this be enough to free the humans and establish a lasting peace between apes and humans?
