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 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.

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."

Natalia Grace was adopted in 2010 by the Barnett family, which included Kristine and Michael Barnett and their three sons. Soon, the Barnetts grew wary of Natalia, who they believed was older than she said she was due to markers such as pubic hair and having adult teeth.
