When Laural finds an injured dog near her house on an isolated ranch, she has no idea of the danger he brings with him. New to the area herself, she finds solace in his company as they investigate the high desert areas around her home. Signs of a stalker soon become evident and Laural finds she has nowhere to turn. Her only contact with the locals are the people she works with at an area hospital where she is an emergency room nurse and a stranger she meets while hiking near her house. Even the sheriff and the veterinarian seem to show up at odd times, leaving her with no one to trust and with time running out.
