改编自陈研一的小说《完美嫌疑人》，以一场看似完美的犯罪为引线，串出表象之下的人性“病态”，裹挟着孩童事件，反照出众生相。
该剧翻拍自同名日剧，试图寻找韩国社会中作为夫妻生活的意义，讲述做出危险选择并拉响家庭战争的夫妻故事。
Chatfah, the youngest sister of the Bupphachinda family, has just received the largest share of her father's inheritance and is about to be married. However, Chatfah falls from the highest floor of a vacation home to her three older sisters' shocked eyes. When her body disappears, her three sisters—Baibua, Chomphu, and Picha—become suspects in her disappearance. The eldest sister Baibua is composed, wise, and has always sacrificed for her family. The second, Chomphu, is a confident model whose boyfriend Chatfah stole and was engaged to. The third, Putpichaya, is a jewellery designer and the closest to Chatfah. The three search for Chatfah while further tragedy befalls them following their youngest sister's disappearance. When no one else can be trusted, the three sisters must try to trust one another. They move back to their childhood mansion to find out who was behind Chatfah's disappearance, which could very well be one of them.
