Humanity returns home. After weeks of landing on Earth, the Centurion manages to create a sense of order in a wild and chaotic environment. But their fragile equilibrium collapses with the arrival of new landers from space. These newcomers are the luckiest—the settlement is running out of oxygen—but after they arrive safely on land, it becomes clear to Glass that her fortunes are running low. Clarke leads a rescue party to the landing craft crash site, ready to treat the injured, but unable to stop thinking about her parents, who may still be alive. Meanwhile, Wells struggles to maintain his power despite the presence of the Vice-Chancellor and his armed bodyguards.
As for Bellamy, he must decide whether to choose to face or run from the crimes he believes he has left behind.
It's time for the Hundred to unite and fight for the freedom they found on Earth, or risk losing everything - and everyone - they love.
