Zoey is a NASA scientist participating in an 18-month experiment to test human hibernation. During her hibernation, a catastrophic event causes the Earth to stop rotating, killing everyone in the facility except Zoey. She is rescued by an AI assistant drone named BEEPBOOP. Together they search for survivors. Zoey establishes a home and farm in the seed vault as the climate changes rapidly. Eventually BEEPBOOP must leave to search for other survivors, leaving Zoey alone hoping BEEPBOOP will return or others will be found.
