A razor-sharp thriller about a mother forced to the breaking point when her life and the lives of her children are threatened by an intruder 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 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. There they hide as the man searches for them, trying to tempt the children out with promises and scare the mother into surrender. In the suffocating darkness, the mother struggles to remain calm, to plan, to search for any opportunity to find a weapon or escape and get help. But then she catches another glimpse of him. That face. That voice. And at once she knows her situation is even more dire than she’d feared, because she knows exactly who he is—and what he wants.
