Sometimes a breach in confidence is all that is required to devastate a family. The Thai original psychological horror film ‘The Whole Truth,’ directed by Wisit Sasanatieng, twists the “peeping Tom” stereotype into a spine-chilling familial mystery. After their mother is killed in an accident, brothers Pim and Putt are forced to live with their grandparents for a time. Putt discovers a breach in the wall that allows the disturbing familial past to seep back into the present. As the titular truth eludes awareness, the final seconds remain hazy. Let us take you back to the house if you want to go over the story’s twist conclusion in further depth. WARNING: SPOILERS AHEAD.

Plot Synopsis for The Whole Truth

Pim and Putt share their home with Latte, their mother’s cat. Pim is the captain of the school’s cheerleading squad. Fame, one of Putt’s friends, spies on Pim when she changes her clothes one night. Pim contacts her mother to alert her of the situation. Mai, their mother, in a high-profile profession that forces her to work the night shift. On her way back, Mai is involved in an accident, leaving Pim and Putt in the care of their grandparents. Mr. Somphong appears to be an uptight man, while grandmother Wan suffers from dementia. Mai falls into a coma as a result of the serious brain injury.

According to the doctor, she has just a fifty percent chance of waking up from her coma. Putt discovers a hole in the wall while roaming around the house. They try to draw their grandfather’s attention to the location, but Somphong does not see any holes. The irritated grandfather retires to his upstairs bedroom, assuming that the children are playing a trick on him. However, the kids gradually learn about the hole’s history. Putt deduces that the room on the other side of the hole resembles their grandparents’ living room, which adds to the mystery.

The End of the Story: Are the Grandparents Dead or Alive?

The grandfather, Somphong Chaiyawan, is a former head of the criminal suppression section. He returns to his old office in search of further information on Mai’s hit-and-run. Apiwat, a real estate billionaire, owns the car involved in the accident. Somphong incorrectly assumes that the tycoon’s son Chaiyut was driving at the time of the tragedy. However, when Chaiyut’s pal admits to the hit-and-run, the tycoon’s kid walks free.

Somphong, dissatisfied with the result, resolves to take matters into his own hands. He puts on his old police costume and goes on patrol, stopping Chaiyut’s automobile in the middle of a tunnel. Somphong spills the whiskey bottle on the tycoon’s son and sets him flame after removing him from his vehicle. Somphong receives a call from the officer on duty in the dying seconds. While new video evidence supports Chaiyut’s innocence in the hit-and-run, authorities have recovered Chaiyut’s charred body.

While Somphong hears Wan crying in the living room, the officer summons him to the police station for questioning. Wan is haunted by the spirit of Pinya, but Somphong sees a half-burned Chaiyut in his place. Somphong only comes to after firing a couple rounds of shots, and by then, Wan is dead. Somphong recognizes after the act that he may have to pay for his horrible actions. He doesn’t want the truth to be out and is willing to put a bullet in his own mouth. The hole reopens when the bullet strikes the wall. Somphong and Wan have both died by this point.

Pinya, who are you? How Did She Pass Away?

Putt deduces later in the novel that the hole could be a wormhole because the room on the other side looks just like their grandparents’ living room. Putt sees his mother Mai through the peephole, younger, pregnant, and holding a baby. She searches for her daughter, whom she refers to as Pinya. Putt and Pim, on the other hand, have no notion who Pinya is. Their grandmother, who has been tormented for fifteen years by the sounds across the wall, eventually begins to spill the beans.

Pinya was Mai and Krit’s first child, and she would be Pim’s elder sister if she were still living. Pinya wanted to play hide and seek while Krit was painting and drinking in the morning. Krit told her to go hide somewhere, so she did, and she locked herself in the spandrel. Krit, on the other hand, had forgotten about his daughter and passed out on the couch. Pinya died after being kept in the closet for a long time and consuming a bottle of rat poison.

However, as the story implies, that is not the entire truth. Wan was not fond of Pinya because of her defects, and she gradually poisoned her by messing with the milk. Similarly, she tries to poison Putt, but Mai saves the day. We later discover that Wan had confined Pinya in the closet. Her shame may be the cause of her dementia, as well as the reason she has been hearing the sounds for the past fifteen years.

Krit’s Cause of Death

Wan’s willful faults had to be paid for by Mai’s husband, Krit. Wan first claims that Krit committed suicide due of guilt. In retrospect, though, we can see through Wan’s lies. However, with Mai’s suspicion, we conclude that Somphong was the one who murdered Krit. Mai is visibly outraged when Somphong enters the house with the same gun that killed Krit. The kids, on the other hand, believe that some shards of the truth are still hidden.

Putt is curious about his father, so Mai pulls out a painting of the family before Putt was born. She blames her parents for destroying the family, but is there any remorse in her wailing? The hole, we later discover, was caused by Mai’s bullet when she shot Krit. On the night of Pinya’s killing, Somphong awakened Krit up with his usual splash of booze, but it appears Mai was the one who pulled the trigger.

Is this a real hole? What exactly is the ‘whole truth’ of the title?

Putt is the one who finds the hole. His sister can see the place as well, but Somphong denies that there is a hole. Putt later takes Fame to his grandparents’ house and shows him the hole. Putt looks through the hole and sees a horrible little specter vomiting blood, but Fame can’t see the hole. He’s still eager to participate, but when he peers through the fictitious hole, something smacks his head against the wall. Pim returns to discover Fame bleeding from the nose.

During the day, the siblings glance through the peephole to uncover unsettling happenings taking place on the other side. In one scene, a weird girl crawls into the room, leaving a trail of blood behind her. In another, Putt peers through the hole in the girl’s head, and in the following frame, the girl vomits blood on a youngster. Pim deduces that something is amiss with the chamber on the other side because it is still dark there. The whole thing seems magical to them, and Pim chooses not to go to the presumably neighboring house. However, Putt awakens at night to see the nasty girl touching Pim.

Pim awakens to Putt’s cry, and by the time she turns on the light, the phantom has vanished. The audience, on the other hand, notices the eerie girl outside the siblings’ room. Putt vomits blood the next morning and does not go to school. When Putt’s grandmother comes to get him a glass of milk, he shows her his drawing book. The last page of the book features a drawing of the girl with the hole in her skull, which irritates granny. When Putt reopens the book after his grandma has left the room, he finds no evidence of the artwork.

When Somphong takes the law into his own hands, Mai flees the hospital to save her children from her evil parents. Putt’s condition worsens, and Wan admits to noticing the hole for the past fifteen years. On her way in, Mai discovers her cat, Latte, dead in the front yard. Latte drank the milk before the glass cracked, therefore we know he drank it. In the living room, Mai quickly deduces that Wan has been poisoning Putt. Somphong returns, and Mai and the children flee the house against his wishes. In retrospect, we can tell that the hole was caused by the bullet that killed Krit.

The hole may represent a vacancy in the family. The final voiceover indicates that the spot is a metaphor for truth. Truth is like a small hole hidden by darkness, but visible when light enters through it. The fact, like the hole, remains hidden in plain sight, and people like Somphong can never perceive the hole since he has been busy denying the truth all along. The closing scene reveals that Wan was the one who confined Pinya within the closet, exposing the titular “full truth.”
