After a devastating confrontation, Abel, played by Ricky Davao, finds himself in a tragic predicament when a passing car leaves him incapacitated while his wife, Gail, portrayed by Jackie Lou Blanco, meets her untimely death in a hit-and-run incident. This accident leaves Abel a widower with two children, Ara, played by Shaina Magdayao, and Abigail, played by Elijah Alejo.
Years pass, and after a visit to their mother's grave, Abigail stumbles upon an old doll in a nearby barrow. Despite a hesitant Ara's warnings to discard it, Abigail develops a bond with the doll, believing it to be a vessel for their mother's spirit. Tension escalates between the sisters, leading to a traumatic incident where Ara destroys the doll, fearing it is malevolent. Abel decides to take drastic measures, ordering the doll to be thrown away in the creek. However, the doll, imbued with a sinister presence, retaliates by killing two garbage men and finds its way back to Abigail's home, intent on enacting revenge.
The dark origins of the doll unravel, revealing its tragic connection to Dorothy Cruz, a woman who succumbed to madness after the loss of her child. In a harrowing confrontation at night, the doll attacks the family. Ara, spurred by the doll's ghastly imitation of her mother's voice, takes control of the situation by firing her father's shotgun at the doll, ultimately saving Abigail from its clutches. But the horror does not end there, as the doll is later seen in the company of homeless children, suggesting its malevolence endures.
In a parallel narrative, the story shifts to Andrea, portrayed by Andi Eigenmann, who, along with her friends Ces and Belle, ventures to a remote island for vacation. Unbeknownst to them, the island hides dark secrets, as rumors circulate about a man named Ray, who lost his girlfriend there under mysterious circumstances. During their stay, Ces performs a ritual intended to help Andrea deal with her heartbreak, but soon after, she mysteriously disappears. When she reemerges, disheveled and muddy, it becomes evident that Andrea's experience involves supernatural forces as she was lured by meddling fairies and an engkanto into a cave where temptations await.
Tensions flare as their group grapples with Andrea's eerie disappearance. Under the guidance of the local witch doctor Malay, they learn that Andrea is now a target for the engkanto, revealing a deeper folklore tied to the island. Their ordeal intensifies as fairies assault their cottage, resulting in fatal consequences for Belle and Ces. In a climactic showdown, Ray, along with Malay, confronts the engkanto. Although Malay meets his own tragic end, Ray bravely defeats the creature, rescuing Andrea—or so it seems. As Andrea regains consciousness aboard a boat with Ray, she soon discovers that this escape was merely an illusion, and she is still trapped in the grip of the engkanto, who assumes the guise of Ray.
Simultaneously, another layer of horror unfolds in the life of Dianne, played by Carla Abellana, who takes a part-time tutoring position with the Gonzales family, owners of a funeral parlor rumored to harbor aswangs.

As the sinister reality emerges and her loved ones are put in peril, Dianne finds herself desperately seeking to protect her family. The sinister plans of the Gonzalez family become crystal clear when they set a trap to ensnare Dennis, forcing Dianne into a horrific choice that threatens to seal her fate as a meal for the aswangs. In a desperate bid to escape, she ignites the funeral parlor in an attempt to gain the upper hand. While fleeing, she inadvertently brings Ryan along, the only family member who shows reluctance towards their ghastly traditions.
As the smoke clears, and Dianne tends to her injured brother, a terrifying realization dawns upon her: Ryan has ulterior motives, revealing his desire to break free from his family's grotesque dietary demands.
