After the great war in 2023, humanity is facing the verge of extinction. To prevent that from happening the remaining people create a diverse country called Axis, which is located in a simulation.
Kalypso is slowly getting used to the life in the In-Between and uncovering the truth about the simulation and the Earth, while scientists in Axis continue to look for her.
The new group members meet up with the rest of the survivors. What happens when Artemis gets a visit from her past? Will she accept the choices she made or be haunted forever?
Xiris wakes up from a nightmare which reminds her of her past. It's the day of her and Harvey's 5th anniversary. What will happen when a scientist finds a suspicious memory signal?
After Beatrix launched the attack the group in the In-Between is trying to stay alive and out of the sight of the humanoids. North tries to take care of Artemis, who is badly wounded, and Harvey is determined to see his fiancée.
As Harvey informs Beatrix about his discoveries, Xiris is visited by Axel. North and Artemis reach the house where the rest of the group is hiding and attempt to break in after seeing the house is swarming with humanoids.
While the group in the In-Between is focused on finding Norah, not knowing what has already happened to her, Beatrix orders Harvey to send Kalypso all of the memories - every single one of them.
