After a high-strung theater producer's behavior turns from demanding to what is believed to be demonic, Kristen, David and Ben must assess the situation. Kristen discredits her nemesis, Leland Townsend, before he can ruin a 17-year-old boy's life.

Kristen, Ben and David are hired to evaluate Eric, a seemingly psychopathic 9-year-old boy; Eric takes a liking to David, which leaves them hopeful they can curb his violent behavior; Kristen's daughters lie about a game their grandmother bought.

On Halloween night, Kristen and David are sent to assess an exorcism; Ben goes on his favorite show, where he debunks supernatural finds with fellow unbeliever Vanessa.

When Bridget confesses to murder during her exorcism, Monsignor Korecki asks Kristen, David and Ben to investigate if the details match any open cases and if the woman really is possessed by a demon.
