After Maximilian Jones is killed in a robbery, his wife Aleksa, whom he met in Saint Petersburg, Russia, names their daughter Jupiter after his favorite planet, and they relocate to Chicago to live with her family. Years later, Jupiter makes a modest living as a housekeeper to her wealthy neighbors. Desiring a telescope, she agrees to sell her egg cells and uses her friend Katharine Dunlevy’s name as a pseudonym. At Katharine’s house, extraterrestrial “Keepers” attack the women. Jupiter photographs them, but they erase both women’s memories of the incident immediately afterwards. She later notices the strange photograph on her phone while waiting at an egg donation clinic, but cannot recall anything about it. During the procedure, the doctors and nurses are revealed as Keepers sent to kill her, but Caine Wise, a former soldier dispatched by Titus to bring her to him, rescues her.
