Sue is determined to keep the children safe, and in doing so, struggles with whether or not she can trust Mother. Meanwhile, a new threat arises and an increasingly erratic Marcus causes the Mithraic to question their leader.
As Marcus continues to embrace his Mithraic devotion, Sue worries he may no longer have her and Paul’s best interests at heart. Meanwhile, Mother experiences what she believes to be malfunctions, and Hunter works on a secret project with Father.
Struggling to maintain his clout as leader of the Mithraic, Marcus begins to make decisions that disturb his family, while Mother's ability to see him for who he truly is threatens his power and puts her in a precarious position. With Tempest on his side, a strong-willed Campion finds himself at dangerous odds with the Mithraic.
After rekindling her connection to her creator, Mother finds herself distracted by intense feelings she didn't know she was capable of having, unaware that Marcus, Sue and the Mithraic are closing in on the settlement.
Marcus moves forward with a plan to rescue the Mithraic children, but first he has to find them. Back at the settlement, Campion and Paul bond while on a hunting expedition with Father, and Mother attempts to learn more about her origins.
Father tries to teach the children how to hunt some of Kepler-22b's mysterious creatures for food. Meanwhile, the Mithraic make a stunning discovery that potentially fulfills a Mithraic prophecy, and a debate about how to proceed ignites a conflict between Marcus and the Mithraic leader, Ambrose.
After the Mithraic kids fall sick, Campion believes Mother is poisoning them and plans an escape. As Mother and Father attempt to prove otherwise, Marcus and Sue work to convince the other surviving Mithraic to mount a rescue of the children, desperate to get their son Paul back.
After a confrontation with Marcus, Mother discovers and takes five Mithraic children (Hunter, Tempest, Paul, Holly and Vita) back to her settlement. While Mother, Father and Campion, adjust to living with a new group of Earth-born children, Marcus struggles to survive alone on Kepler-22b.
After Earth is rendered uninhabitable, Androids start a settlement and a new family with human embryos on the planet Kepler-22b.
