Adrienne Fuller is used to working late hours and long nights. As a nurse, her job is to save people, but when she witnesses a wreck on the road in front of her home and sees the men involved leave a dead body in a crumpled car, saving anyone is the last thing on her mind. This was no accident, and she's already learned a hard lesson about the criminal justice system. She vows to tell no one what she saw, even the cops who come knocking on her door the next day.

Henry "Zan" Duncan is deep undercover investigating a human trafficking ring, and in his line of work he has to pretend to be the bad guy. During a horrendous car chase, it's either kill or be killed. When he spots a woman with fiery red hair hiding in the bushes, he goes back the next day to save her life, unaware he just raised the stakes on his mission, blew his cover, and failed in his effort to never fall in love.

Dodging bullets, fights, and explosions, Adrienne must learn to trust the man who claims he wants to protect her, and Zan must open his heart to the woman he is starting to love.
