Seven days after moving into their new home, Diana receives a mysterious call from the previous owner claiming a forgotten camera caught her husband Marcus and his mother Cheryl doing something secretive while she was at work, with an urgent warning to come alone and tell no one. As she watches Marcus and Cheryl exchange knowing glances and hand her oddly-timed paperwork back at the house, Diana quietly grabs her keys under the pretense of a grocery run.

Arriving at the previous owner’s bungalow, she finds him nervous and apologetic, guiding her to a laptop already paused on a frame of her empty living room. As he presses play, Diana braces herself for whatever truth Marcus and Cheryl never expected her to find.
