*4bia*, also known as *Phobia*, is a chilling anthology horror film comprised of four distinct segments, each exploring the dark consequences of human guilt, obsession, and the supernatural.The first segment, "Happiness," follows a lonely, reclusive young woman living in a dilapidated apartment who communicates with the outside world solely through text messages. She strikes up an
online relationship with a mysterious, injured stranger. As their intimacy grows through shared photographs and affectionate messages, she remains blissfully unaware that her correspondent is actually a decaying corpse lying in the apartment across the hall. The tragic climax reveals the chilling truth when the man’s decomposing body is finally discovered by authorities, leaving the terrified woman trapped alone with the vengeful spirit she inadvertently invited into her life.The second segment, "Tit For Tat," plunges into the brutal world of high school bullying. A timid, studious teenager named Khun is relentlessly tormented by a cruel gang of peers. Driven by humiliation and a desperate desire for vengeance, Khun turns to ancient, forbidden black magic. He purchases a cursed textbook and casts a powerful, fatal spell on his tormentors one by one. However, black magic demands a terrible sacrifice. As the violent retribution unfolds through grotesque hallucinations and flesh-rotting curses, Khun realizes too late that the dark forces he unleashed cannot be controlled, leading to a horrifying finale where the curse ultimately consumes him as well.The third segment, "Middle Man," centers on four friends on a camping trip who constantly bicker over trivial matters and play dangerous practical jokes. During a late-night rafting excursion, their raft capsizes in treacherous rapids. One of the friends, Ter, seemingly drowns in the chaos. The survivors return to their tent, traumatized, only for Ter to reappear, soaking wet, acting strangely, and claiming he survived. Believing Ter has returned as a malicious ghost, the remaining friends panic and attempt to banish or destroy him, leading to a chaotic, paranoid struggle of survival. In a darkly comedic and startling twist, it is revealed that Ter actually survived the river, and his panicked friends accidentally murder the living boy in their blind, supernatural terror.The final segment, "Last Fright," stars a
flight attendant named Pim who is forced to work a solo night shift on a private charter flight serving a controversial, arrogant royal princess. Pim harbors deep guilt because she recently had a torrid affair with the prince, who is the princess's husband. When the princess dies suddenly from a severe allergic reaction onboard, Pim is ordered to accompany the corpse back home in the desolate, dimly lit cabin. Trapped in an enclosed space at thirty thousand feet with the dead body, Pim is stalked by the princess’s wrathful ghost, culminating in a desperate, claustrophobic fight for her life against the inescapable past.
