PLOT
After the mysterious death of his father inside their newly built house, Nguyễn Văn Ân lives with his mentally deteriorating mother as a series of unsettling supernatural events begin to unfold. In an attempt to uncover the truth, Ân starts documenting everything through a vlog series titled Spiritual Stories in My House (Chuyện tâm linh trong nhà mình). During his investigation, he discovers an ancient talisman buried beneath the foundation and gradually realizes that the house is connected to a Lu Ban curse ritual passed down among construction workers — tied to a rumor that after nine ordinary houses, a mysterious “tenth house” is chosen for a dark purpose never meant to be revealed.
