Where the origins of evil meets science and religion is the premise of CBS Television Network’s new psychological mystery, EVIL, which debuts Thursday, September 26.

Created by Robert and Michelle King and directed by Robert King, it stars Katja Herbers, Mike Colter, Aasif Mandvi, Michael Emerson, Brooklyn Shuck, Skylar Gray, Maddy Crocco, and Dalya Knapp.

In the series premiere, Kristen Bouchard (Herbers) is a skeptical female psychologist, who divides her days between her patients and acting as an expert witness determining whether defendants are capable of standing trial.

After one trial, she is approached by David Acosta (Colter) a priest-in-training. He invites her to join his team to investigate the Catholic Church’s backlog of unexplained mysteries, including supposed miracles, demonic possessions, and hauntings. He doesn’t care when Bouchard states that she no longer believes in the supernatural. Their job, he explains, is to assess if there’s a logical explanation or if something truly supernatural is at work. He values her skepticism to provide a balance in their investigations.

Their first investigation surrounds a man on trial as a serial rapist/murderer, who exhibits characteristics of demonic possession. Bouchard offers plausible reasons for the man’s behavior, but when strange things begin happening in her own life, she begins to question those reasons.

The characters are believable and the acting strong. Herbers plays Bouchard as a tough-skinned single mom trying to do her job while raising her daughters. Colter portrays Acosta as a world-weary man on a spiritual quest for truth. The storyline is engaging. There are a couple of, “oh, come on now,” moments; but there are also enough ‘what if’ moments to make viewers question their own beliefs.

EVIL airs Thursdays, 10:00-11:00 PM, ET/PT on the CBS Television Network.
