When Elena, a new tenant in Flat 2B, starts hearing strange dragging sounds above her late at night, she sends a hesitant voice note to the building’s maintenance man, Mark. He reassures her it’s probably nothing — except the flat above hers, 2C, has been empty for months.
As the sounds grow heavier and more deliberate, Elena’s late-night messages become increasingly panicked. Mark tries to piece together what’s happening from a distance, uncovering unsettling details about the supposedly sealed apartment upstairs.
