Irene is the mother of the bride, but her ex-husband Toby would have been more pleased had she stayed in Canada and skipped the wedding. Even Ellen is indifferent to her mother's descent upon them, since she hasn't seen Irene since Ellen was five. But when Irene is murdered at the reception, the police wonder whether she was the target, or whether the bride or groom dodged a death meant for one of them. Ellen's cousin, actress Tessa Crichton, has her own ideas.
