Home alone with her young children during a blizzard, a mother tucks her son back into bed in the middle of the night. She hears a noise—old houses are always making some kind of noise. But this sound is disturbingly familiar: it’s the tread of footsteps, unusually heavy and slow, coming up the stairs. Shrouded in the shadows, she sees the figure of a man appear down the hallway. Terrified, she quietly wakes her children and hustles them into the oldest part of the house, a tiny, secret room concealed behind a wall.

July 1995. April and Eddie have taken a wrong turn. They’re looking for the small resort town where they plan to spend their honeymoon. When they spot what appears to a lone hitchhiker along the deserted road, they stop to help. But not long after the hitchhiker gets into their car, they see the blood seeping from her jacket and a truck barreling down Atticus Line after them.

Emma hasn't told her husband much about her past. He knows her parents are dead and she hasn't spoken to her sisters in years. Then they lose their apartment, her husband gets laid off, and Emma discovers she's pregnant—right as the bank account slips into the red. That's when Emma confesses that she has one more asset: her parents' house, which she owns jointly with her estranged sisters. They can't sell it, but they can live in it. But returning home means that Emma is forced to reveal her secrets to her husband.

After their mother passes, three estranged siblings reunite to sort out her estate. Beth, the oldest, never left home. She stayed with her mom, caring for her until the very end. Nicole, the middle child, has been kept at arm’s length due to her ongoing battle with a serious drug addiction. Michael, the youngest, lives out of state and hasn’t been back to their small Wisconsin town since their father ran out on them seven years before.
