What is the plot?
The episode opens with Detective Ryo Narita arriving at the Haikawa Mansion under a heavy snowfall, where police have cordoned off the area after discovering the skeletal remains of 13 children buried in the basement.
Narita, haunted by his own past loss of a younger sibling, examines the scene closely, noting the small skeletons arranged in a circle with traces of cloth remnants suggesting they were dressed in identical uniforms.
He interviews the current mansion owner, Kohinata Fumiyo, an elderly woman who claims she bought the property years ago unaware of its history, her hands trembling as she clutches a family photo.
Narita presses her on the previous owners, learning the mansion belonged to the Haikawa family, who vanished decades ago amid rumors of isolation and strange rituals.
Flashback sequence begins: Young Haikawa family patriarch, played by Hagiwara Riku in youth, decides to cut off all external contact after his wife's death in childbirth, vowing to protect his growing brood of children from the world's cruelty by raising them solely within the mansion walls.
The children, initially joyful, start showing signs of malnutrition as the patriarch enforces strict rationing, believing scarcity builds character, while he hoards food for himself.
One child, the eldest daughter, secretly attempts to escape through a basement window during a storm, but slips on ice and fractures her leg, crying out in agony as snow buries her screams.
The patriarch discovers her, drags her back inside by the arm, breaking it further in the process, and locks her in the basement as punishment, deciding this will teach obedience to the family unit.
Narita finds a hidden diary in the mansion attic belonging to that eldest daughter, detailing her failed escape and growing despair among the siblings.
Back in present, Narita confronts Fumiyo with the diary, accusing her of knowing more; she breaks down, revealing she was the family's live-in maid as a teenager, named Ai Yoshikawa in her youth.
Flashback continues: Teenage Ai, played by Yoshikawa Ai, joins the Haikawa household desperate for work, initially charmed by the patriarch's talk of unbreakable family bonds.
She witnesses the children weakening, one by one fainting from hunger, but the patriarch forbids her from intervening, claiming it's a test of loyalty.
Ai tries to smuggle food to the children at night, slipping bread through the basement door where the eldest daughter is confined, whispering encouragements.
The eldest daughter, delirious from pain and starvation, begs Ai to help them all escape, but Ai hesitates, fearing the patriarch's wrath.
Another child dies overnight in the basement, his body going undiscovered until morning; the patriarch gathers the remaining children, declaring the deceased "too weak for the family," and orders them to bury the body themselves in the basement soil.
Narita pieces together the timeline from the diary and Fumiyo's reluctant testimony, realizing the burials formed a ritualistic circle to "preserve the family eternally."
In present, Sato Taiki as Narita's partner arrives with forensics confirming the deaths spanned years, all from starvation and exposure, with no external trauma.
Flashback escalates: Ai discovers she's pregnant from a forced encounter with the patriarch, who claims it's to expand the family; terrified, she decides to flee with the children.
She confronts the patriarch in the kitchen, stabbing at him with a knife during an argument over rations; he disarms her easily, slamming her head against the counter, leaving her unconscious and bleeding.
Regaining consciousness, Ai finds the children locked in the basement, the patriarch barricading the door with furniture, announcing they will all "starve together as true family."
Ai pounds on the door, pleading, but the patriarch ignores her, sitting upstairs eating the last stores of food while the children wail inside.
Days pass; Ai, weak from her injuries and pregnancy, digs frantically at the basement foundation from outside, but collapses in the snow.
The patriarch, succumbing to his own starvation, stumbles downstairs one final night, unlocks the door intending a last reunion, but finds most children already dead, including the eldest daughter who used her dying strength to strangle him with her chains.
Ai survives barely, crawling out a window, miscarries in the snow, and flees the mansion, abandoning the scene out of overwhelming guilt and trauma.
Narita arrests Fumiyo/Ai, who confesses fully, explaining her return decades later to buy the mansion was an attempt at atonement by preserving the site.
As police excavate the final remains, Narita finds a locket with a photo of Ai and the children, triggering his own emotional breakdown as he recalls his sibling's unsolved disappearance.
Fumiyo/Ai, handcuffed, whispers to Narita that true family means passing on protection, even through sacrifice, before being led away into the blizzard.
Narita stands alone in the empty mansion, snow piling against the windows, vowing silently to uncover any remaining secrets.
What is the ending?
In the finale of Episode 3, Detective Jin Saeki uncovers a crucial clue linking the 2017 Haikawa mansion murders to a present-day disappearance, but the episode closes on a tense cliffhanger with Kanon Hasumi confronting a shadowy figure from the past, leaving Saeki racing against time as the true culprit's identity remains elusive.
Now, let me take you through the ending of Episode 3, scene by scene, as the tension builds in this gripping human suspense drama.
The scene opens in the dimly lit interior of the old Haikawa mansion at night, rain pounding against the cracked windows. Detective Jin Saeki, portrayed with weary determination by Ryo Narita, stands alone in the dusty room where the skeletal remains of the thirteen children were discovered seven years prior. His flashlight beam sweeps across faded photographs on the wall showing Juzo Haikawa, the missing mansion owner played by Fumiyo Kohinata, surrounded by the children who called him "Father." Saeki's face tightens as he spots a small, mysterious mark etched into the wooden floorboards--a symbol identical to one found at a recent crime scene in 2024 Tokyo. He kneels, scraping at it with his knife, his breath visible in the cold air, muttering to himself about the connection to the missing girl from the group of young escapees.
Cut to Kanon Hasumi, played by Ai Yoshikawa, driving through the stormy Tokyo streets in her car, her knuckles white on the steering wheel. Her eyes, filled with a mix of fear and resolve, reflect the passing neon lights. She's heading to a rundown apartment where one of the six survivors from the mansion lives. Earlier in the episode, she'd claimed to adore Haikawa as a father figure, but now doubt flickers across her features as she grips a photo of the group. She parks, steps out into the downpour, her coat soaking through, and climbs the creaky exterior stairs, water streaming down her face.
Inside the apartment, Jun Suzuki, portrayed by Taiki Sato, paces nervously. He's one of the survivors, his hands trembling as he clutches a phone. The door bursts open--Kanon enters without knocking, dripping wet. "You knew about the mark, didn't you?" she demands, holding up a sketch of the symbol. Jun backs away, sweat beading on his forehead despite the chill. He stammers denials, insisting Haikawa was innocent, that the children lived happily under his care, escaping society's cruelties. But Kanon presses, revealing a hidden letter she found earlier, implicating someone else in the deaths. Jun lunges for it, they struggle, papers scattering across the floor. In the scuffle, Kanon notices a fresh version of the mark carved into the windowsill.
Suddenly, the lights flicker out. A shadowy figure emerges from the bedroom doorway--Seiji Kawai, played by Tooru Nomaguchi, another survivor, his face gaunt and eyes wild. He holds a knife, the blade glinting. "You shouldn't have come here," he whispers. Kanon freezes, Jun cowers behind her. Kawai confesses he was protecting the group's secret communal life, but the missing girl in 2024 has stirred old wounds. He claims Haikawa vanished to atone, not because he was guilty. The figure steps closer, raising the knife toward Kanon.
Intercut with this: Saeki receives a tip on his phone while still at the mansion. It's from an anonymous source--a blurry photo of Kanon's car outside the apartment. His eyes widen; he bolts from the mansion, jumping into his unmarked police car, sirens blaring as he speeds through the rain-slicked roads toward Tokyo. The dashboard clock shows 2:17 AM. His brother, Sosuke Takimoto, played by Riku Hagiwara, calls him--Sosuke, who has been shadowing the investigation unofficially, warns Saeki that the survivors are closing ranks, hinting at a larger network tied to the 2017 imprisonments.
Back at the apartment, Kawai corners Kanon against the wall. She pleads, "The children didn't deserve to die alone like that." Kawai hesitates, revealing his motivation: loyalty to Haikawa, who saved them from abusive families, but someone else orchestrated the killings to silence them. Just as he swings the knife, the door explodes inward--Saeki bursts in, gun drawn, having tracked her phone. "Drop it!" he shouts. Kawai whirls, but slips on the wet floor from Kanon's soaked clothes. He crashes into a table, the knife skittering away. Saeki tackles him, cuffing his wrists as Jun cowers in the corner.
The police swarm the apartment minutes later, lights flashing outside. Saeki questions Kanon roughly: her real connection to Haikawa? She admits she was one of the children, escaped but haunted, now seeking truth. Kawai, in custody, laughs bitterly, saying the real culprit is still free--someone from the 2024 group of young hangouts mirrors the mansion survivors exactly.
Fade to black on Saeki staring at a wall of photos in the precinct: the thirteen dead children, Haikawa's face circled, the six survivors including Kanon, Jun, Kawai, and others like Sosuke linked by red string to the new missing girl. A final shot lingers on the mysterious mark glowing under UV light, pulsing like a heartbeat.
As for the fates of the main characters in this episode's ending: Jin Saeki survives the confrontation unscathed and recommits to unraveling the past-present link, physically exhausted but mentally sharper. Kanon Hasumi escapes physical harm, her emotional turmoil deepening as her survivor past surfaces, positioning her as Saeki's reluctant ally. Juzo Haikawa remains missing, his innocence or guilt still ambiguous through others' accounts. Jun Suzuki is detained for questioning but not arrested, trembling and silent. Seiji Kawai is arrested on suspicion of assault and possible involvement in covering up the murders, dragged away protesting his loyalty. Sosuke Takimoto, Saeki's brother, stays on the periphery, unharmed but drawn deeper into the shadows of the case. The missing girl from 2024 hangs in unresolved peril, her fate tying directly to the mansion's ghosts.
