Shadowy figures lurk in Lee Thongkham’s stylised horror, which wrongfoots the audience with jump scares aplenty

Thai writer-director Lee Thongkham’s horror feature is a giddy, gory little treat. Unfortunately, it’s hard to explain exactly what’s so fab about it without spoilers, so just take our word for it as long as you have the stomach for lots of fake blood and jump scares. Suffice to say that Thongkham is nimble when it comes to wrongfooting the viewer, and there’s some pleasingly pointed satire here as well, sticking it to rich, snobby people who think domestic workers are as disposable as empty washing up bottles.

The maid of the title is Joy (bob-haired ingenue Ploy Sornarin), a country girl who gets hired to schlep tea trays up and down the stairs in service to super-wealthy Uma (actor-model-singer Savika Chaiyadej), a woman so ridiculously haughty she dresses like a gameshow hostess for breakfast and always uses a cigarette holder – presumably so the butts don’t touch her lips. Joy has worked out that she’s but the latest in a long line of maids who don’t last long in that household, but when she asks the other servants they get all squirrelly and tell her she’s not to ask any questions.
