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.

Both viewers that have been tracking Natalia Grace's wild life story for years and those who just discovered the messy, drama-filled world of the Ukrainian-born orphan are in for huge twists as the third and final installment of The Curious Case of Natalia Grace drops bombshell after bombshell.

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.
