Charlize Theron is giving us chills in the latest trailer for her upcoming thriller Dark Places.
Based on the New York Times best-selling novel of the same name by Gone Girl author Gillian Flynn, the Academy Award winner plays Libby Day, a survivor and the sole witness of a Kansas massacre that claimed the lives of her mother and sisters when she was just eight years old.
Libby's brother, Ben (House of Cards' alum Corey Stoll) then a teenager, was one of the suspects, and her testimony helped lead to his conviction.
But nearly thirty years later, Day is forced to confront her past when she teams with a secret society of amateur investigators, dubbed The Kill Club, to find out what really happened.
"I was 8 when they were killed," Theron says in the eerie trailer. "The little girl of the Kansas prairie massacre."
She later encounters Lyle (Nicholas Hoult), a member of The Kill Club" who notes that her brother has been in jail for 28 years.
"If you're trying to convince me that Ben's innocent, you're wasting your time," Theron tells him before he replies, "I'd just like to pick your brain about what happened that time."
In typical Gillian Flynn fashion, the story then takes a number of twists and turns as Theron tries to get to the bottom of the brutal murders.
"I'm sad for you little girl," Ben creepily tells his sister when she visits him in prison, "You're just as imprisoned as I am."
Theron previously spoke out about the intense role in a new interview with French television network TF1 and revealed she "can relate" to her character due to her own personal family tragedy (Theron was 15 when her mother shot and killed her father after he apparently fired his own gun into Charlize's bedroom following a night of drinking and making death threats).
"My character goes through this event when she's 8 years old, and it really is examining what trauma does to a child, especially when she's expected to speak about it," the actress said. "And that's definitely something I can relate to, that's definitely something I've experienced in my life."
She added: "As far as events go, they're very similar. There's a murder [in the film], while my situation was a very unfortunate incident with self-defense."
Dark Places, which also stars Christina Hendricks and Chloë Grace Moretz, hits theaters August 7.
