As Middleton prepares for its annual Halloween Fall Festival, Cassie's neighbor, Sam, volunteers to set up a hay maze for it, hoping to bond with his son, Nick. While Cassie tries to bring them closer together, she struggles to get her own family - daughter Grace, step-children Brandon and Lori, and cousin Abigail - together to transform Grey House into the town's most popular haunted attraction, under the watchful eye of Mayor Tinsdale. Abigail is too busy campaigning against Stephanie in a heated competition for festival queen. Grace, bullied at school by two teen femme fatales calling her a witch, begs Cassie to put an end to their annual tradition. As Cassie welcomes a secretive stranger, Joseph, to Grey House, she soon finds her intuition is no match for whatever is causing trouble for her family. While Brandon and Lori investigate Joseph's past, Cassie discovers a deeper connection that could put the whole community in danger.
