A brother and sister following in their mother's footsteps as apprentice shamans spend their days honing their respective spiritual abilities, but when their mother travels to a remote mountain village and fails to return, the siblings set out to find her, only to come face to face with a shocking truth connected to the legendary blood demon "Phi Phong," whose terror has gripped the entire village. Amid a string of gruesome, horrific deaths, the siblings fight desperately to rescue their mother from Phi Phong's curse, and in the process, they encounter a suspicious mother and daughter whose mysterious motives remain unclear. Rooted in traditional folktales and legends passed down through the mountainous regions of northern Vietnam, this film is a genuine horror work that effectively combines the distinct appeals of folk horror and occult cinema. While anchoring itself in a primal fear of supernatural forces, the narrative simultaneously carries the warmth of deeply human emotion, offering a poignant resonance that extends far beyond mere fright. In particular, the rich world-building—which draws extensively on local legends and indigenous beliefs—creates an atmosphere of singular originality distinctive to Southeast Asian horror, pulling the audience into profound immersion. A notable box-office success upon its theatrical release in Vietnam, this finely crafted film stands as an accomplished work that delivers both the enduring charm of traditional folklore and the chilling pleasures of genre cinema in equal measure.
