Trevor MacDaniel is a search and rescue volunteer whose need to guard and protect extends to his daily life. When he rescues a boy from a mountain lion, he forms a bond with Natalie Reeve, the sculptor next door whose gift is also a disability. Their relationship develops, but a reckoning draws near. Drawn by the heroic story of the boy's rescue on the news, a twisted mind recognizes its adversary in Trevor. The threats Trevor receives chill him and those he cares about, but are, at the root, a cry for help. Jonah Westfall, chief of police, has not encountered a threat like the one approaching his town, Redford, Colorado-- but he'll do whatever it takes to bring it down.
