All Cassie Nightingale wants for her birthday is for her family and friends to be together. While her husband, Jake, suggests an intimate dinner at a fancy restaurant in their hometown of Middleton, Cassie would rather have a party at The Grey House with all her loved ones in attendance. And since Jake's kids, Brandon and Lori, are growing up with lives of their own, it might be their last chance to unite as a family for a long time. Meanwhile, Grandpa George's new wife Gwen discovers that her prodigal son Drew has returned to Middleton after a five-year absence with plans to get married. When a business deal turns bad, however, it jeopardizes Drew's impending nuptials and sets him on edge. It's just one in a series of unfortunate events that, one way or another, traces back to Cassie and her store, Bell, Book and Candle. As Cassie's special day fast approaches, Lori discovers disturbing parallels between Cassie and Cassie's great aunt, nicknamed the Grey Lady, who disappeared at her own birthday party years before. With signs of a curse looming over her, it's clear that Cassie needs to conjure up more than a little magic to make things right again.
