Tom Parsons' days are interrupted by an unsettling and peculiar stoppage of time. He dubs these terrifying events The Sleep and when they occur, he is left in a state of complete limbo, with nothing active but his eyes and mind.

At first, he questions his own sanity. But when a sound cuts through the stillness, he realizes something else is out there.

Watching. Waiting.

Detective Kate Strathmore is hunting for a missing woman, and all signs point to Tom. But a chance encounter with a homeless man - who speaks of true evil lurking in the frozen moments between time - gives her pause.

As Tom, Kate, and the old man confront the darkness hiding inside these moments, they find themselves in a fight for their lives... Because while others are asleep in the stillness, something else is wide awake.
