Kate Carpenter, the front-of-house manager of Calgary's largest theatre company, has just returned from a well-earned vacation after the murder of a patron in her theatre's lobby and the mayhem of the ensuing investigation left her more than a little stressed. She had been looking forward to a return to normality - working at the theatre, adjusting to her new life with her boyfriend, Cam, and planning a surprise birthday party for her chief usher, Graham. Nothing more exciting than that. Instead, what she gets is a flooded concert hall that results in a huge piano competition being moved to her theatre. From there, the appearance of her old college boyfriend - along with his wife and daughter - followed by a surprise visit from her mother and a dead body hanging from the second balcony of her theatre can only mean more problems for Kate. Trying to juggle friends and family, past and present, Kate unwittingly embarks on another murder investigation, which leaves her with a clearer picture of her future - and of who is most important to her now.
