Sadie moves back in with her estranged sister, Chloe and her teenage daughter Nicole. Nicole is a troubled teenage girl, but she has one true fried, Shay. Derek is her boyfriend, and he seems to make Nicole a happy girl again.
The movie really focuses on Sadie as we see how unhinged she becomes, as she starts to tear the entire family apart. Nothing will stop her to get what she wants, even if that means hurting the people she supposedly loves.
The actress that plays Sadie is the entire reason to spend the time to watch. She chews up the scenery every time she is on screen. Especially as we ride along with her, in her descent to madness.
