After a global apocalypse, an android called “Mother” is responsible for repopulating Earth using a collection of embryos stored in an underground failsafe bunker. Her teenage daughter, who she raised from an embryo, is submitted to classes and tests to assess her development as human being. When the daughter finds a mouse inside the base, she suspects that the outside is no longer contaminated. One day, she sees a wounded woman outside the base and lets her in. Soon she learns something that will affect her relationship with Mother and which will change her forever.
