1945, Shanghai. When Zhan Zhou-shi (Ziyi Zhang) a woman stripped of her birth name, dismembers her abusive gambler husband Big Rock (Chuanjun Wang), she?s arrested red-handed. But as ambitious cop Xue Zhiwu (Jiayin Lei) rushes to close the case, 31 witnesses deliver contradictory accounts: Was she a battered wife fighting back? A pawn in a conspiracy? Or a monster? Amid media sensationalism and corrupt officials, Zhan finds unlikely allies in jail: a cynical dancehall queen (Mi Yang) and a feminist writer (Liying Zhao) who turns her trial into a public reckoning on women?s rights. As the line between victim and avenger blurs, one truth emerges: Her crime wasn?t murder - it was reclaiming her voice.
