The film combines evil spirits, ghosts, reincarnation and other horror elements to tell the story of a child who was once Su Yun (played by Chen Farong), who was killed by Didi, returned to her old house after a long absence. She encountered the reappearance of her brother's evil spirit and possessed Gumantong to seek revenge and seek revenge.
2. "Gumantong", commonly known as "Golden Boy" or "Buddha Boy", is a "strange sacred object" that has been circulated in Thailand and Southeast Asia for a long time, and can bring unexpected wealth to the donor. Children are often used to eliminate disasters for donors and bring blessings and wealth. In the hands of folk wizards, Gumantong is mostly made from the ashes or bones of deceased children. However, Gumantong in temples do not use such materials. And it also needs to be blessed by eminent monks and magicians, because in front of Thai Buddhism, these are detrimental to the moral character.
