Darling (2015)

In need of a full-time caretaker to look after her house, an elegant madame hires a lonely young woman. However, this is not an ordinary place. Indeed, her eerily silent residence is the oldest building in the city: a rumour-riddled mansion tarnished with hair-raising stories of occult rituals and hauntings. But with such a wicked reputation, most people would turn down the enigmatic lady's lucrative offer--of course, this dark-eyed steward couldn't care less about gossip. Now, peculiar sounds and blood-curdling occurrences inside the hauntingly vacant apartment's long corridors foretell an ominous fate. Why is that room at the end of the dark hallway off-limits? If the tormented keeper is the house's prisoner, will she ever rid herself of the ever-growing voices inside her head?
