The Kinema Junpo critics were, of course, mistaken to think that Naruse had abandoned his emphasis on women. His next film, Sincerity, features two strong female characters, played by Irie Takako and Murase Sachiko, each of whom have a daughter. The girls are schoolmates, but one (Nobuko) is from a middle-class home and the other (Tomiko) is from a poor family. Tomiko's mother Tsutako (Irie) is a single mother who works from home as a seamstress, while Nobuko's mother lives in an elegant home with her husband, Kei. Eventually, it is revealed that Kei had a romantic relationship with Tsutako, and may be Tomiko's father as well, but he is conscripted shortly after this revelation and goes off to war.This is very much a home front film, in which the women are involved in supporting activities, and the whole town cheers on the new recruits. As Kei is a banker, he is conscripted as an officer. He is introduced brandishing a magnificent sword, indicating his readiness for his call-up, for which everyone congratulates him when it comes. The wartime context is little more than a backdrop to the story of paternity and former love. The complex emotions among the women are conveyed through cutting on eye movements and eye lines, and through the use of the pastoral location.

某晚，警察局来了一个不速之客军（王宝强 饰），他向当值探员报称自己杀了五个人，但他既说不出与受害者关系，又不能描述出受害者被杀过程或遇害地点。原来只是计划把五人杀死。探员在记下军的联络住址后便把他驱逐，在探员眼中，他只是一名无聊的精神不正常者。可是不久，督察汉（刘青云 饰）驻守的区域却发生了一件凶杀案：死者形状恐怖，汉认为这种处死方法带有不寻常的动机，不到一星期汉接手另一宗凶杀案，死者也是一名男子，死于一个废置的机械工场。他的死法十分残酷，死者的双脚被强行穿上细尺码的红色高跟鞋，脚面和两侧都钉上了十多口的铁钉。汉在翻查全港可疑人物和案例时，看到了当天军前来自首的记录。汉马上带队前往军的住所进行搜查，可是屋内空无一人，除了大量古旧童话书外，并无可疑之处。但这时候汉还不知道，一张被精密预设的大网张开了，而结局却更是匪夷所思，难以预料。
