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 reveals why she finally cut ties with her adoptive parents after fleeing their home to live with another family -- and the moves she's making to take "control over my life."

The third season of the ID channel docuseries brings to light allegations of financial and physical abuse against Natalia’s new adoptive parents, Antwon and Cynthia Mans; THR reached out to the Indiana Police Department about the allegations.

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.

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.

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.

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.

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.
