In the TV movie My Stepdaughter, teenager Casey has a dark past and she’s not willing to let go of it. The arrival of her new stepmother, Jill (Emmanuelle Vaugier), doesn’t help. Jill tries her best to connect with Casey but the teenage girl is evil. It’s not an opinion. When Casey kidnaps Jill’s 9-year-old daughter Lydia, Jill realizes Casey also had something to do with the death of Jill’s handicapped mother who died suddenly, and mysteriously.
Stepdaughter Casey is portrayed by Niki Koss. The 21-year-old Los Angeles native is best known for her roles in Red Wing, the 2013 film based on the George Sand novella The Country Waif, starring with Bill Paxton and Frances Fisher, and in the 2014 horror, The Appearing with Dean Cain. You can see Koss next in the dramatic film Girl on the Edge and the comedy/horror Scouts Guide to the Zombie Apocalypse with Patrick Schwarzenegger and Cloris Leachman. My Stepdaughter will air on LMN on September 28 at 8pm, on September 29 at 12am, and October 2 at 6pm.
