During a buffalo photo shoot, wildlife photographer Nikki Lancaster snaps a picture of an odd man who later follows her to her car. She races away, only to have a vehicle run her off the road and leave the scene of the accident. When the first officer on the scene is DCI Agent Xavier Palinski, her ex-fiancé, Nikki figures things can't get any worse. She's wrong. Days later, Nikki discovers a dead body in that same area. After search teams find the bodies of three other women, Nikki suspects she hasn't just photographed a crazy tourist. Instead, she's captured a serial killer on film. Chafing at the ridiculous safety measures forced on her by Xavier and her family, Nikki can't escape the feeling that safety is an illusion. Eventually, the evil she encountered will not only haunt her dreams but will destroy her, her family, and any glimmers of a second chance at love.
