Amateur cinematographer Cleo Moss hasn't tried to make a film since her father's death three years ago. Her cousin Noah, a director, is convinced that her latest script is the perfect opportunity to try again, but Cleo is less sure. Those reservations grow when a blizzard nearly runs them off the road on their way to the shoot, and again when they discover that the house they're filming in has a tragic past to rival Cleo's own horror-filled writing. By the time she starts seeing ghostly shadows out of the corner of her eye, she's convinced that the production is doomed.

At first, filming moves forward in spite of an unreliable camera battery and Noah's surprise casting of Isobel, Cleo's not-so-former crush. But as the worsening snow traps cast and crew in the house overnight, the strange shadows escalate into horrifying, dangerous specters. While the rest of her friends fight to find a way out of this nightmare, Cleo can't help but be drawn to the ghosts she captures in her viewfinder-just as she can't help noticing how similar their story is to her own past...
