About the movie

While Christine,[2] a children's fashion designer, takes a call, a dog approaches and spreads ticks onto her before vanishing. One tick attaches itself to the nape of her neck, subsequently debilitating Christine with a mysterious illness. A woman named Diana arrives at her home, claiming to be the caregiver Christine had hired. Christine's husband, Felix, and daughter, Bobs, are both distrustful of Diana. After settling in, Diana unpacks her suitcase, revealing a collection of relics and folk magic ingredients. She uses a matchbox to summon and capture the tick that bit Christine, then assembles an altar in her room's fireplace and uses its ashes in a ritual to commune with the unseen spirit of a child.During dinner, Christine gets sudden pains in her arms. Diana comes to her aid and cures Christine by hovering her hands over her arms then tickling her until the pain disappears. Diana explains that she possesses supernatural powers which she received in childhood from a dying old woman who was an ongo looking for someone to transfer her powers to after death. Diana then swallowed a black chick that exited the woman's mouth and approached her. Diana subsequently used her powers for her income but became a social pariah after she is deemed to be a witch.Christine allows Diana to treat her, with positive results. Despite this, Felix remains wary of Diana. He confronts Diana in her room and orders her to stay away from Christine. A defiant Diana suggests he leave, telling him ominously to be careful with the stairs. As Felix is about to descend, he is attacked by Bobs' pet canary, which he kills after hitting it in panic. As Diana and Christine bond while burying the bird, Felix senses that Diana is responsible for the incident and fears she is driving a wedge between him and his family.After Christine's medications go missing, Felix searches Diana's room and discovers the altar and the drugs under Diana's bed, prompting him and Christine to fire Diana. Before departing, Diana asks Bobs to do her a favor. The following day, Bobs tells Christine that Felix hid the drugs to frame Diana, prompting a fight between Christine and Felix. As Felix moves upstairs to cool-off, he is attacked by a canary that resembles Bobs' pet and is injured after falling from the top of the staircase. Felix is hospitalized, while Diana returns to care for a relapsed Christine.As Diana performs a final ritual for Chistine, she reveals that she isn't curing Christine, but punishing her. Christine then sees flashbacks of Diana's life in the Philippines where she lived happily with her husband and daughter until they were expelled by landgrabbers and fled to Cebu City. Diana was forced to work at a sweatshop used by Christine to produce her clothing line and took her daughter with her. During a visit, Christine advised the managers to overwork the employees and lock the only exit to prevent theft, which resulted in the death of Diana's daughter and her coworkers following a fire. Diana, who happened to be outside at the time, subsequently hexed Christine by sending her a spectre of the dog. As Christine begs for forgiveness, Diana calls her a tick and makes Christine physically experience the fire and face Diana's badly burned daughter.As Felix arrives to find Christine's burnt body seated at her sewing machine, Diana tells Bobs to wait in the garden. She then climbs to the roof and jumps to her death in front of Bobs. A black chick emerges from Diana's mouth and enters Bobs', making her an ongo. Back in Cebu, Diana's spirit bids her husband goodbye.The film ends with Bobs alone in the woods collecting herbs while being watched over from afar by the spectre of Diana. (thanks to Wikipedia)
