　　1945年，上海酱园弄发生一起骇人血案，一石激起千层浪。詹周氏（章子怡 饰）为何杀夫？又如何凭一己之力完成碎尸？随着时代变迁，她的命运又将如何改写？大时代下鲜活的众生群像又将如何展开？

Set in a bustling alleyway during the Japanese occupation of Shanghai in the 1940s, the film centres on a wife, Zhan Zhou, who was being charged with the bloody dismemberment of her husband – a killing that seems impossible for her to have committed alone. The murder thrusts Zhan into the spotlight and the court of public opinion, forcing her towards a fate intertwined with that of her own country.
