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 David recognizes one of the sigils in the Poveglia Codex from his father Leon's artwork, he and Kristen journey to a remote art commune to investigate its meaning and how it's related to David's family.

The team is sent to investigate the disappearance of a teenage boy, Wyatt.

Ben, David, and Kristen investigate the RSM Fertility clinic - since so many of their past cases have led back to the ominous clinic.
