A heartbroken Sidney agrees to help parishioner Isabel prepare for her wedding to Arthur, the new man in town, but the bride's stubborn mother, Daisy, proves to be a big impediment to the occasion as she believes the groom is out to kill her. When Daisy is then found dead, Mrs Maguire calls in Geordie to investigate, and Sidney finds himself dragged into the case - despite vowing to leave police business behind. While the victim seems to have died of natural causes, Arthur and Isabel are pushing for a fast cremation, suggesting the couple have something to hide.
