Plot Synopsis

THE CURIOUS CASE OF NATALIA GRACE is a three-part documentary that explores a mystery ripped straight from the headlines: Who is Natalia Barnett? Initially assumed to be a 6-year-old Ukrainian orphan with spondyloepiphyseal dysplasia, a rare bone growth disorder that can result in skeletal abnormalities as well as issues with hearing and vision, Natalia was adopted by Kristine and Michael Barnett in 2010. However, the happy family dynamic soured when allegations against Natalia were brought by the Barnetts who alleged Natalia was an adult masquerading as a child with intent to harm their family. In 2013, Natalia was discovered living on her own which ignited an investigation that led to Michael and Kristine's arrest and a firestorm of questions. Featuring exclusive bombshell interviews with members of Natalia's adoptive family including father Michael Barnett and brother Jacob Barnett, as well as relatives, friends, legal experts, and neighbors of Natalia and the Barnett family, THE CURIOUS CASE OF NATALIA GRACE offers a never-before-seen glimpse into the Barnett family, Natalia's identity, Michael Barnett's October 2022 trial, as well as key insights into new theories and evidence. Unfolding over multiple parts and three consecutive nights on ID, the docuseries presents an unparalleled deep dive into this shocking family saga tracing all the way from Natalia's birth in Ukraine up to the arrest and subsequent legal proceedings around Michael Barnett on charges of neglect.
