Ghosts, murder, meta commentary, all backstage of a production of Shakespeare's Scottish Play (begins with Mac, ends with Beth). When the star of the show is murdered, Rosalind, the stressed out stage manager, and Beatrice, the gentle leading lady, are the only ones who have the brains to solve the mystery. Everyone's a suspect and nobody feels ready for opening night which, in case we didn't mention it, is tomorrow! They question the cast and crew and discover that everyone had means, motive, and opportunity except for the concierge, Robin Puck. That's when the second murder occurs. With the show running onstage and the culprits running backstage, Rosy and Bea have a mess on their hands.
