Jiang Jianwei married into the He family three years ago. Her husband kept a mistress, embezzled her dowry, and even publicly handed her a divorce letter at his birthday banquet. She neither cried nor made a scene. Instead, she produced a separation agreement, account books, and a legal complaint, reclaiming her property and opening a divorce agency specializing in helping women with marital separations, broken engagements, and property disputes. As one case after another comes knocking, she discovers a sinister trafficking network involving marriage brokers, powerful aristocrats, and a Deputy Minister of Revenue. Armed with evidence, Jiang Jianwei breaks through their schemes and leads thirty-seven women in submitting a petition to the imperial palace. She helps the victims escape their gilded cages and transforms her divorce agency into the capital's foremost legal petition office.
