A trailer for Gillian Flynn's crime novel series Dark Places was released Thursday, and in it, characters Libby Day and Lyle are among many who are introduced.

Libby, played by Charlize Theron, is the survivor of her family's murder she witnessed in the 1980s. She was a little girl at the time and was convinced that her older brother Ben, played by Corey Stoll, was the murderer of their mother and two older sisters.

However, after meeting up with Lyle, played by Nicholas Hoult, she isn't sure Ben was, in fact, the killer. Lyle is a part of a secret society consisting of former private detectives, cops, lawyers and more who are obsessed with solving cold case, closed and notorious crimes. With the help of this society, Libby will track down her past in order to reveal the truth about her family's murder.

The story in the novel appears through flashbacks and setting back into the present. Whether the film will do the same thing is still uncertain.

Other cast members who join Theron, Hoult, and Stoll, are Chloë Grace Mortez as Diondra, Christina Hendricks as Patty Day, Drea de Matteo as Diane, Andrea Roth as Old Diondra, Glenn Morshower as Jim Jeffreys and Laura Cayouette as Krissi Cates' Mother.

This is the second novel of Flynn's that will be made into a motion picture. Gone Girl was released last year and was nominated for an Oscar. Flynn wrote the screenplay for the film and won several awards for it. Flynn did not, however, write the script for Dark Places.

Dark Places does not have a release date for United States yet but it will release in France on April 8.
