A strange white bubble fifty meters in diameter was discovered one day in a town in western France. She lures and captures three-year-old Leo, Elodie's son. Other bubbles appear, grow, and humanity fails to destroy them. Their increasing magnetic activity is disrupting electrical and digital networks, leading to unprecedented technological regression. Only the "absorption" of very young children seems to slow down their expansion... Will the fear of disappearing push humanity to promulgate Isaac's law? But can you raise a child knowing that it will be taken from you at the age of three? Camille, who herself has lost a son, and her friend Basile, of Malian origin - a ufologist by profession - will try to unravel the mystery of the white ladies in order to avoid a return to barbarism.
