Keller County precision marksman Cadence Holly, a member of the Sheriff's Emergency Response Team, believes she doesn't have anything to prove to her new unit because her she's good at what she does. Detective Brody Remington, a former military sniper, along with the rest of their unit, disagrees. Brody spends most of his time berating Cadence, until she proves him wrong by making a shot he can't beat.
Brody regrets the way he's treated Cadence. As he struggles to get back into her good graces, Eugene Dunham, a man seeking revenge for his brother's arrest and subsequent murder, targets Brody. Once Dunham realizes Brody and Cadence have formed a bond, he sets his sights on Cadence, setting up a frightening game of cat and mouse that can end only one way. Will Brody get to her in time?
