Synopsis

Housewife Mizusawa Asako tolerated her mother-in-law’s persistent nit-picking and let a two-generation household be established. Before long, her mother-in-law, a constant source of worry, passes away and Asako is released from the nightmare of living together under the same room. However, two years later, a fateful day arrives that would affect her life. It is the wedding ceremony of her only son Yuta and his bride Ririka, and also the day Asako debuts as mother-in-law. In the first place, both Asako and her husband Hiroyuki opposed this marriage. However, Yuta and Ririka hold their ground. A distressed Asako unthinkingly tossed living with the parents as a condition for marriage, expecting Ririka to refuse. However, reality was different. Ririka accepted this with a smile. This led to the wedding ceremony on this day. Asako resolves to be kind to Ririka, but at the same time feels a vague foreboding. Before long, the newlyweds return from their honeymoon. Asako frets about dealing with Ririka by herself, but when she starts drinking alcohol with her daughter-in-law, she chats animatedly about her problems with her late mother-in-law and husband’s history of affairs. The two of them hit it off with each other and Asako thinks that peaceful relations between mother-in-law and daughter-in-law will be built. However, the next day, Asako, who gets out of bed with a hangover, sees that her “perfect daughter-in-law” has already tidied up and prepared breakfast. But Ririka’s behaviour makes Asako end up feeling it is a peculiar scheme. Furthermore, this is followed by an improper conversation of Ririka’s that she happens to listen in on and she gets more and more suspicious of her. The relationship between mother-in-law and daughter-in-law sour as if last night’s closeness was a lie. Around that time, mysterious disappearances occur in the residential neighbourhood where they live. The atmosphere around Asako grows turbulent. And then, police detectives finally reach out to the Mizusawas … …
