Hulu's "Good American Family" is inspired by the true story of Natalia Grace Barnett. Ellen Pompeo plays Kristine Barnett, Natalia's adoptive mother.

Based on the real-life saga of Natalia Grace, the show follows her adopted mother and father, Kristine and Michael Barnett, as they become increasingly suspicious that their new child isn't actually a child after all.

Ellen Pompeo 's new Hulu show Good American Family — her first project since stepping back from Grey's Anatomy — is a true-crime series based on the story of a Midwestern couple who adopted a child with a rare form of dwarfism. They eventually come to believe that the child isn't a little girl at all, but rather an adult conwoman.
