When Nat dies and unexpectedly returns as a ghost inhabiting a vacuum cleaner, her disgruntled in-laws believe the solution is simple—just unplug her. But Nat isn’t leaving quietly. Determined to protect her dust-allergic husband and prove her worth in the afterlife, she embarks on a mission to rid the house of malicious spirits and establish herself as a truly “useful” ghost. Playfully blending supernatural comedy with sharp political undercurrents, A Useful Ghost is both a delightfully camp spectacle and a subversive reflection on Thailand’s layered histories. Bold, bizarre, and utterly original, this is one of the most unique cinematic experiences of the year.
