Arkangel plot
After losing her daughter Sarah, Marie (Rosemarie DeWitt) decides to participate in an Arkangel company trial. They have developed a chip that is injected and through which a parent can then see where the child is, ensure that shocking images are automatically filtered and see everything from the child's point of view. When Sarah is still young, this gives the mother a lot of security, but automatically filtering images by making them blurry and being able to watch them at any time causes problems as Sarah gets older.
