A Sister's Obsession

Kendra has been given an Educator of the Year award and now must prepare a speech to give at a banquet in her honor. She has the support of her husband (and is trying to start a family with him) and best friend Monica, but her life is starting to unravel. Kendra will discover the cause is a long lost twin sister, Amber, who resents her twin's "entitled" position. Kendra must fight her vindictive sister to save her home, husband, job, and finally her life.

Directed by David Langlois, A Sister's Obsession leans on a strong ensemble — Lindsay Hartley, Jason Cermak, Candice Hunter — to carry a story that balances spectacle with character.

The film landed with audiences for its craft and performances, and remains one of the most talked-about thriller titles of 2018.
