The 4th Floor1999

Horror Vault's take

When a young woman inherits a coveted rent-controlled apartment in New York City, what seems like a stroke of luck quickly curdles into a waking nightmare. A relentless, unseen neighbor below begins a campaign of harassment that escalates far beyond normal dispute territory. The film traps its heroine — and the audience — in a pressure cooker of doubt and dread, blurring the line between reasonable fear and full-blown paranoia. With a strong lead performance from Juliette Lewis, this late-90s thriller mines genuine terror from the mundane anxieties of apartment living.
