Small town beach girls Esther and Sophie are happiest working in the school library, surfing, and hanging out with Parker and Paisley, twins from Britain. Esther has always hidden behind her cardigan and glasses, but Parker's handsome face and brilliant mind convince her to risk going on a date with him. When the best-selling author of Blessed Be announces she will film part of her movie in their Oregon Coast town, Esther and Sophie get a job tutoring the celebrity stars playing the parts of the witches and warlocks. But when Parker is cast as an extra, strange things start happening on set. To find the killer, the girls ditch the library, take bit parts in the movie, and travel to a castle on a seaside cliff. Not everyone survives, but everyone is a suspect!
