What Is 4bia About?
The premise of 4bia in 278 words, with nothing given away. The full story follows below.
This anthology film weaves together four distinct horror tales, each rooted in the unsettling territory of human vulnerability. Bound by the central theme of facing one’s deepest fears, the stories move between modern urban isolation, the cruel dynamics of youth, an isolated wilderness journey, and the quiet dread of an airliner cabin. Together they form a chilling portrait of how terror can take many forms — physical, emotional, social, and supernatural.
The first tale centers on a young woman named Pin, confined to her apartment after an accident that has left her injured and dependent on her phone for connection to the outside world. The second follows a quiet young student named Ngid, caught in the brutal hierarchies of school life. The third introduces four friends — Aey, Ter, Shin, and Phuak — whose river-rafting trip through a remote jungle takes an unsettling turn. The final story features Pim, a flight attendant whose routine assignment aboard a chartered plane leads her into an eerie and unexpected situation.
Each segment is steeped in atmosphere, using familiar settings — a lonely apartment, a schoolyard, a wild river, an aircraft cabin — to build creeping dread. The film draws on Thai cultural beliefs and folklore, lending its horror an intimate, distinctly regional texture. The tone shifts fluidly between psychological unease and overt supernatural terror, creating a layered experience where ordinary moments twist into something far more sinister.
Through these four interconnected stories, the film offers a haunting reminder that fear often arrives when we are most alone, most vulnerable, or unable to escape. The horror feels personal rather than apocalyptic, rooting itself in quiet places where dread waits patiently to surface.

Pin, a young woman restricted to her apartment due to a leg cast, relies heavily on her cell phone and text messages to maintain a connection with the outside world. She confesses to her boyfriend her deep sense of loneliness, illustrating her isolation. During the nights, Pin engages in text exchanges with a mysterious stranger who seeks her friendship and claims to be in a place he describes as “cramped” for a duration of 100 days, intriguing but strange in its own right since he can only be contacted at night. Upon sharing a photo of herself, she eagerly requests one in return, only to receive back the same image. Confused, she pushes for clarity and learns that the figure beside her in the image is a ghostly face.
As Pin delves into research about recent fatalities, she uncovers a haunting backstory: a man who had passed away was buried with a cellphone to keep in touch with his mother or to reach out whenever he felt lonely. Suddenly, she receives an alarming text from the stranger stating he is coming to her place. With the lights flickering and darkness enveloping her, terror grips Pin as she is violently attacked by the ghost, leading to her fatal fall from her window.
The narrative flashes back to reveal the tragic end of a young man who, heartbroken by a breakup communicated through a text message, decided to take his life by stepping in front of a taxi. This very incident was responsible for Pin’s injury.
In another unsettling thread, a nerdy student named Ngid suffers a brutal beating at the hands of schoolmates while one of his friends, Pink, is helplessly aware but unable to intervene. Ngid, in his pain, curses his peers with a deadly charm, a curse which involves a photo of a deceased person with their eyes open. Strangely, as Ngid’s spirit takes hold, disturbing occurrences begin to escalate, leading to the demise of the drug users involved. The curse does not spare Pink, despite her having not participated in the assault, as she witnessed his persecution but opted to do nothing. A police officer arrives, warning her against venturing outside just as she falls into madness, having gouged her eyes out in a desperate attempt to escape Ngid’s supernatural retribution.
Meanwhile, a group of four friends — Aey, Ter, Shin, and Phuak — embark on a river rafting adventure in the secluded jungles of Chiang Mai. Around the campfire, Aey shares an ominous prediction: should death befall him, whoever sleeps in the middle will follow. The following day, tragedy strikes when Aey is thrown from the raft and tragically lost. Despite an exhaustive search, his friends eventually accept his disappearance and set up camp for the night, tensions rising over who will sleep in the middle, ultimately settling on an arrangement that allows all to avoid it.
Later that night, as strange happenings unfold, Aey returns to the camp, raising unsettling suspicions among his friends. When Shin steps outside for a smoke, he uncovers the gruesome truth of Aey’s lifeless body. The horrifying realization dawns: the four have all perished in the river’s depths, yet only Aey accepted his fate, while the others stubbornly clung to the life they once had. In a bittersweet conclusion, the four friends must confront their new existence bound together as spirits.
On a different note, Pim, a flight attendant, is secretly entangled in an affair with Prince Albert of Virnistan. Tasked with piloting a charter flight carrying Princess Sophia, the prince’s wife, the day unfolds into a nightmare. When Tui, her fellow stewardess, is unable to fly due to her brother’s drowning (a link to the previous story), Pim finds herself alone in a precarious position. Tragedy strikes during the flight when the princess experiences a severe allergic reaction to shrimp in her meal, resulting in her untimely death.
After the royal family urgently requests the return of the princess’s body for cremation, Pim is compelled to remain onboard and oversee the transport of the sole passenger, an unnerving responsibility that forces her into unsettling proximity with the enshrouded corpse. What was meant to be a routine return flight devolves into chaos as Pim’s worst fears manifest. Upon landing in the United Kingdom, an alarming discovery awaits: Pim is found deceased on the cabin floor, lying beneath the shrouded body of Princess Sophia. The tragic events intertwine their fates, emphasizing the notion that even in the air, death knows no boundaries.
