It’s been two months since Teresa last went outside. After surviving a car accident that claimed the life of her best friend, Teresa is terrified of leaving the security of her bedroom. Since then, her only window to the outside world has been the online community she found through streaming—the friends she games with, a small following of her own, and her favorite internet personality, Brick.

But one night, Teresa’s virtual barriers start to break down when a shadowy figure appears in the background of Brick’s livestream. Over the next few days, she watches with thousands of others as his behavior mysteriously changes. And then the unspeakable happens.

As the first person to catch footage of the deadly specter, Teresa finds herself at the center of a life-and-death investigation to find out who or what this figure could be. To defeat this relentless force, she must venture beyond the mental and physical walls she’s created. But will she be able to conquer her fears before anyone else loses their life?
