<p>Chatfah, the youngest sister of the Bupphachinda family, has just received the largest share of her father&#39;s inheritance and is about to be married. However, Chatfah falls from the highest floor of a vacation home to her three older sisters&#39; shocked eyes. When her body disappears, her three sisters—Baibua, Chomphu, and Picha—become suspects in her disappearance. &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<br/> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;　　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&#39;s disappearance. &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<br/> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;　　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&#39;s disappearance, which could very well be one of them.</p>
