When Pierce's racket interferes with the Posse's attempts at making a movie for a contest to win a new camera, Polly, Lila, Shani and Nicholas fake a ghost attack, which prompts Pierce to call in a paranormal investigator named Paranormal Patty, whose tech picks up on the locket's mystical energy. But when Pierce learns Patty intends to destroy the house to protect the neighborhood, he and Polly team up to fake getting rid of the ghost (portrayed by Shani) to save their home before their parents find out about the trouble Pierce caused.
