Mae technoleg newydd Guan a Dr. Sheng yn lladd unrhyw obaith oedd ar ôl ar gyfer etholiad teg. Gyda help Toph, Su, a Kuvira, mae Korra yn dechrau cynllunio i achub pawb a chafodd eu dal gan Guan!

Kuvira’s true nature is revealed, and the Earth Kingdom will feel the consequences! Thanks to Commander Guan and Doctor Sheng’s brainwashing technology, all hope for a fair election in the Earth Kingdom is lost. Korra works with Toph, Su, and Kuvira to plan a means to rescue not just the brainwashed Mako, Bolin, and Asami, but everyone else caught up in Guan’s plan! With the Earth Empire potentially on the rise again, Kuvira pulls another trick from her sleeve… but whose side is she truly on?
