David, Kristen and Ben assess whether a pregnant woman is possessed when she claims one of the twins she’s carrying is evil. Their investigation leads to a fertility clinic where they discover a connection to all of their encounters throughout the season. Also, Kristen questions one of her daughters’ capacity for evil upon realizing that she also used that fertility clinic.

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