Noise (2004)

Joyce Chandler (Trish Goff), a young divorced woman and recovering alcoholic, moves into a Manhattan apartment that seems a bit too secluded to be true. It is: Upstairs lives Charlotte Bancroft (Ally Sheedy), a woman with a wall of obliviousness who can turn even an 'apology' into a guilt trip, Charlotte persists in making Joyce's nighttime hours a living hell. As the torture continues, Joyce starts to lose her grip on her job, her health and her sanity. It's a heck of a price to pay for having your own place.
