This supernatural revenge thriller tells the story of Joy (Ploy
Sornarin), a young woman from the country, who travels to the city
to work as a housemaid at the fabulously wealthy house of Uma
(Savika Chaiyadei) and Nirach (Teerapat Sajakul). Joy is the
replacement for their previous maid who suddenly ‘resigned’ in
mysterious circumstances. Her duties include the care of their
young daughter Nid (Keetapat Pongrue) who suffers with frightening
hallucinations that are attributed to a rare hereditary brain
condition.
Mrs. Wan (Natanee Sitthisaman), the head housemaid, tells Joy that
there are two unbreakable household rules – never pry into the
master’s business and never enter the mistress’s bedroom. Joy
experiences odd occurrences as she wanders the eerie house and is
confronted by the apparition of another maid, a ghostly presence
that only she and Nid can see. Ignoring Wan's warning she sneaks
into Uma's study at night and finds a photo of Uma, Nirach, and
housemaid Ploy – Joy’s sister who disappeared years ago.
