An accident. An attack.

She will do anything to save her daughter.

Anything.

Martina has failed as a mother, and nobody's been more vocal about that than her daughter Jenny. All Martina wants to do is get herself and Jenny home safely, but their road trip goes awry when something monstrous attacks their car on a blizzard-swept mountain road. What began as a way for mother and daughter to reconnect turns into a desperate fight for survival.

A storm traps them inside a meager shelter. A monster stalks them from the woods beyond. And, when Martina discovers the fatal secret Jenny's been keeping, she will sacrifice everything to keep Jenny alive.

Everything.
