Description：Surgeon Zhang Jiaer (played by Annie Liu) and Jessica and Amy are good sisters who grew up in an orphanage. After entering society, they still live together and are very close. One day, Jiaer received a letter from a lawyer, saying that her grandma (played by Paw Hee Ching) in Malaysia had passed away not long ago, and left Jiaer a big house as an inheritance. Jiaer lived in Malaysia when she was a child, but when she came to Hong Kong, she almost forgot everything before. After much hesitation, Jiaer decided to go to Malaysia with her two friends. Under the arrangement of the lawyer, the three came to grandma's quaint house. All the procedures seemed to be going smoothly, but strange and terrifying events happened one after another. In the house where grandma was not there, it seemed that something was wandering around, and Jiaer's long-lost memory gradually recovered.
