In a small town in Mississippi, two witches let their ambitions overrule good judgment, as they summon a powerful demon in hopes that he will help them gain favor and power within their coven. When their offered vessel attempts escape, the summoning circle is broken and the vessel killed, leaving the witches at the mercy of the freed dark entity. With the witches dead, Abaddon is free! 

As head investigator of the Lemont Paranormal Research team, Collin Fitzgerald has his hands full, trying to keep the team focused on work. A job in Georgia introduces a powerful psychic named Shera to the group. She helps them get rid of a troublesome spirit, and Collin reluctantly offers her a job. Things get complicated, as Han and Collin decide they want to pursue a relationship with her. 

Collin accepts a new job in Mississippi, and with it, chaos erupts. Shera's ever developing abilities lead to a startling revelation, as the group finds themselves face to face with the demon Abaddon. A horrific encounter leaves a member of the team in ICU and the rest of the group scrambling for answers. They quickly discover that things are far worse than they thought and leaving the house did little to keep them safe. With a demon out for blood, will the team survive?
