When widowed piano teacher Margaret Halberg opens her quiet home to Delia, a polite young woman seeking temporary shelter, it seems like a simple arrangement: no guests, shared chores, a one-month trial. Margaret craves routine. Delia offers warmth. And the house, once filled with silence, begins to feel alive again.

But something's not quite right.

Delia cooks, cleans, and listens—but also asks questions no one else dares. She lingers too long in the hallway. Notices too much in family photos. And beneath Margaret's politeness lies an unease that builds with every whispered phone call and missing pill.

As Margaret's health falters and memories resurface—letters never sent, names never spoken—the lines between guest and threat, truth and invention, begin to blur. Delia may not just be renting a room... she may be returning to a life that was never hers to begin with.

Who gets to claim a legacy built on silence?

And when the past walks through the front door wearing a smile, how do you know if it came for peace... or for reckoning?
