A distant lake house in Wisconsin. A call to police emergency is cut short. A phone glitch or something more sinister? Off-duty deputy Brynn McKenzie goes to find out.

And stumbles onto the scene of a murder. Before she can call for backup, she finds herself the next potential victim. Deprived of her phone, weapon and car, Brynn flees, along with the only survivor of the crime.

These unlikely allies can survive only by escaping into the dense, deserted woods, on a desperate trek to safety. And ultimately to a life or death choice. Flight. Or fight?
