Murmurs (2004)

Over the course of one week in a shadowy Wellington flat, four flatmates gradually aggravate and menace each other as pressure builds over unpaid bills, a mysterious disappearance, infidelity, and unrequited sexual desire. The physical and psychological claustrophobia becomes increasingly unbearable as they begin to encroach on each other's spaces, culminating in a shocking scene of humiliation and despair.
