Twelve-year-old Zach is cautiously optimistic. His father Bram, whose business is in dire need of cash, has put together a father-son backcountry ski weekend to wine and dine his biggest investors. Schooled in outdoor survival by his mother, Zach is eager to prove himself to the hypercritical Bram. Maybe if Zach shows how useful he is, he can earn his father’s love. But Zach knows to be on high alert around Bram, and he sees the way the group ignores the increasingly threatening conditions. For the first time in his beloved mountains, he is faced with the unknown, convinced that something watches their cabin from the treeline. Something that leaves behind strange tracks and picks its prey clean. As the adults recklessly test the limits of the outdoors, Zach worries he might be in even more danger than he realized.

Home alone with her young children during a blizzard, a mother tucks her son back into bed in the middle of the night. Suddenly she hears footsteps coming up the stairs and 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 and to plan. Should she search for a weapon or attempt escape? But then she catches another glimpse of him. 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.
