The stage adaptation of Jane's book endures numerous snafus before opening night: electrical problems, feuding cast members, and a notorious arts critic writing a potentially bad review. Meanwhile, Mattie searches for new clues in the case of her missing mother, but an onstage murder brings her to the theatre.

Contending with another murder and a missing lead actress, the theatre company is forced to switch up the cast, but their production is a mess. Despite Mattie's objections, Beth and Cat continue to pursue leads on their own.
