She spends her summer vacation trying to uncover the real mysteries of Twin Elms with George and Bess, while trying to get along with Helen… and discovers that maybe this ghostly ordeal goes deeper than she once thought.

Still, she remains unconvinced, standing by the notion that logic trumps above all. Ever a skeptic, Nancy is shocked when the supernatural seems to come to life when she stays at Flora’s home. Nancy, a meddler unable to sit still, is curious about Flora’s predicament, and asks her father (Sam Trammell) if she can sleep over to see this ‘haunting’ for herself. At night, strange mishaps keep occurring, leading Flora to believe that her mansion is haunted. Nancy is forced into half-hearted community service where she overhears Derek’s preppy girlfriend Helen (Andrea Anders) and her great Aunt Flora (Linda Lavin) pleading with the sheriff (Jay Devon Johnson) to investigate Flora’s house, the Twin Elms estate. The friends break into his gym and spray-paint his entire body blue, only to be caught in the act. She and her best friends George (Zoe Renee) and Bess (Mackenzie Graham) decide to pull an elaborate prank on a notorious bully, Derek (Evan Castelloe), as revenge for embarrassing Bess on social media.
