Lucy never got the chance to win "Most Likely to..." anything. When a head-on collision cuts her life short, Lucy is left to haunt her bereaved friends as they finish high school. Without her, the group is lost- Jackson, Lucy's best friend, most of all. Swept up in a séance, Lucy materializes in The Grimoire, the local occult emporium owned by acid-tongued psychic Artemis. This opens her eyes to new possibilities: with some help from her friends and a ritual from one of Artemis' books, Lucy could be back from the dead in time for graduation. The gang gathers in the woods, along with Adrienne, the popular girl responsible for the fatal crash. But her pals are no experts, and Lucy isn't the only one on the other side looking for a way in. When the rite goes wrong, Adrienne becomes possessed by a spirit claiming to be Lucy. (It's not). How long will it take the crew to realize there's a demon in their midst? Can Lucy save everyone from beyond the grave?
