Episode One - Genesis 1
Kristen Bouchard (Katja Herbers) cuts ties as an expert witness for the District Attorney after being pushed to lie in court regarding an alleged murderer who appeared to be possessed. To make ends meet, she accepts a job offer from David Acosta (Mike Colter), a former adventure-seeking journalist now studying to be a priest and tasked by the Church to assess unexplained phenomena.
Rounding out the trio is Ben Shakir (Aasif Mandvi), an even-tempered realist recruited by Acosta for his carpentry skills, which he uses to uncover practical rationales behind "hauntings".
Ever logical, Kristen is certain science can provide answers to every incident they encounter - including her own chilling real night terrors. That is, until she meets Leland Townsend (Michael Emerson), a sinister man who oozes menace and threatens her and her family. Undeterred, Kristen, David and Ben set out to assess inexplicable events to see if there's a logical explanation or if something truly supernatural is at work.
