A Useful Ghost

In a haze‑shrouded Thai metropolis where relentless construction churns up clouds of dust, the line between the material and the uncanny blurs. The city’s restless modernization has left its inhabitants coughing and its factories groaning under the weight of old grievances. Within this unsettled landscape, a modest apartment becomes a focal point for the supernatural when a newly purchased vacuum cleaner begins to whisper with an unseen presence. The atmosphere is simultaneously wistful and absurd, a darkly comic meditation on loss, memory, and the pollutants that linger far beyond the physical.

March, a gentle and grief‑stricken husband, is still reeling from the death of his beloved Nat and the unborn child they were to raise. As he navigates his sorrow, Nat’s lingering affection refuses to fade; her spirit finds an unlikely anchor in the very appliance meant to cleanse his home. Their fragile bond draws the attention of a nearby electronics factory, now stalled by an angry specter—the restless soul of Tok, a worker who perished on the job. The factory’s heir, Suman, confronts the haunting that threatens to shut down the enterprise forever, while a quick‑acting repairman named Krong offers explanations that are as enigmatic as they are unsettling.

The film weaves together bureaucratic inertia, familial expectations, and the quiet yearning of a ghost determined to prove her worth. Against a backdrop of incense‑filled temples, fluorescent office lights, and the perpetual whir of machinery, the characters grapple with the question of what it means to be “useful” when the line between life and afterlife is so porous. Their intertwined desires—to revive a dying plant, to heal a broken heart, and to reconcile the living with the lingering—create a tone that is simultaneously tender, eerie, and laced with sly humor, inviting the audience to wonder whether redemption can truly be vacuumed up from the dust of the past.
