Iceland’s Olaf de Fleur Johannesson directs a talented line-up of British actors - Florence Pugh, Celia Imrie, Ben Lloyd-Hughes - in a heady horror that utilises the tropes of the genre to genuinely terrifying effect. Isolated haunted house? Check. Creepy orphans? Check. Slow-build tension that something awful is afoot? Absolutely check.
A brother-sister duo (Ben Lloyd Huges and Florence Pugh) who make money pretending to be paranormal investigators find themselves in a very real danger when they are hired by a former headmistress (Celia Imrie) to examine a haunted orphanage in Scotland, where three girls were murdered decades earlier.
