At a local wedding, Mma Ramotswe bumps into a long-lost friend, Calviniah, who confesses that her only daughter Nametso has inexplicably turned away from her. Not only that, an old acquaintance has simultaneously lost all her money and found solace in a charismatic ex-mechanic turned reverend, who seems to have cast a spell over several ladies in the region. With little work on at the agency, Precious and her colleague Mma Makutsi see no harm in investigating these curious situations. Meanwhile, part-time detective Charlie is anxious. He has few prospects and little money, so how can he convince his beloved Queenie-Queenie’s father to approve of their marriage? As Precious and Mma Makutsi dig deeper into the stories of Nametso and the mysterious reverend, Precious once again ponders the human condition. She chooses to believe in goodness, that if our hearts are open, true equality can be found with one another. But in this world, can that assumption be justified? It will take all her ingenuity and great moral sense to get to the heart of the matter.
