After escaping what seemed to be a nightmare living with former adoptive parents Michael Barnett and Kristine Barnett, Natalia Grace moved on to a new life with Antwon Mans and Cynthia Mans, a couple who adopted the disabled Ukraine native after finding her living on her own in Lafayette,

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."

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 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.

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.

Anna Newlin, who once lived with the Mans family, defends the Mans family on camera, but then suggests to producers of the show that Natalia was struck with a belt and kicked down a flight of stairs by the Manses. "There's some things that can land [Cynthia] and Antwon in jail for a long time," she says in a voiceover.

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.
