As Wonder Woman speaks at a Peace Day Conference in New York City, a young girl passes out apples to spectators. Then suddenly, the crowd becomes angry and turns violent. In the center of the chaos, a fire erupts, and Ares, the god of war, emerges from the flames. His daughter, Eris, has created enough anger with her Golden Apples of Discord to refuel her father's evil superpowers. But when Eris is wounded, he must strike a deal with Wonder Woman - save his daughter, or he will destroy the world!
