A girl is raised by a robot, but what's outside their home?

After a world war kills most humans and contaminates the Earth’s surface, Daughter is the first of a new generation of humans to be raised by Mother – a kind robot, programmed to repopulate the lifeless planet.

As Daughter matures into her teens, she outgrows the bunker she calls home and begins to question the nature of the world around her. One dark and lonely night, she plans to defy her protective “Mother” and explore the Earth’s toxic surface for herself. But as she nears the bunker’s door, she hears the pained cries of a woman, bleeding from a gunshot wound – begging for help.

Shocked by the Woman’s existence, Daughter takes her in. The Woman informs Daughter the surface is habitable and that the only threat outside the bunker is artificial intelligence – responsible for killing the humans. When the Woman learns that the girl’s only parent is a robot, she pleads with Daughter to return her to the surface before it’s too late. But Daughter is not quick to part with the first human she’s ever met and hands the Woman over to Mother, insisting that she save her.

Mother gives medical aid and confesses to Daughter that the Woman’s claims about A.I. are correct – though not applicable to herself. Mother reassures Daughter that she had no choice but to shield her from the truth to preserve their relationship. Daughter learns anything she can about their new guest, where she came from, and whether or not there are other survivors in need of shelter.

But the Woman’s trust is not easily gained. After Woman tries to kill Mother, she’s locked up and Daughter learns that she has been living in underground mines with other refugees. The Woman offers to welcome Daughter into her “family” – if Daughter sets her free and leaves Mother, who she insists is a threat to them both.
