Natalia Grace was first brought to the U.S. in 2008 by the Ciccones before being adopted by the Barnett family and later the Mans family

Natalia Grace Mans (née Barnett) was adopted by Cynthia Mans and Antwon Mans after she escaped alleged abuse from her former adoptive parents, Michael Barnett and Kristine Barnett. However, the Mans family may not have been the heroes that the Ukraine native needed.

In the final episodes of the ID series, Natalia's continued communication with her prior adoptive family wreaks havoc on the DePaul household as they try to help her understand how she's been exploited.

The Final Chapter takes viewers behind the scenes of Natalia Grace’s rocky relationship with her adoptive parents and her dramatic attempt to escape from the Mans family.

Viewers are in for a ride when "The Curious Case of Natalia Grace: The Final Chapter" returns for its third and final season in January. The Investigation Discovery series follows Natalia Grace, a Ukrainian orphan with a rare dwarfism condition, as she "is forced to navigate a number of seemingly insurmountable challenges," per a press release.

The series follows the Barnett family, who initially adopted what they assumed to be a 6-year-old Ukrainian orphan with spondyloepiphyseal dysplasia, a rare bone growth disorder.

Michael and Kristine Barnett adopted a Ukrainian girl named Natalia Grace, whom they believed to be 6 years old. However, the couple soon began to suspect that she was an adult con artist who wanted to kill them.

In three seasons, "The Curious Case of Natalia Grace" has examined Natalia's troubling and traumatic life story, bouncing from foster homes to many different adoptive parents after coming to the U.S.
