Betrayed by her FBI boss and nearly killed, Olivia Williams quits and joins Blackhawk Security. But when she runs into Jake Dunbar — the agent who was supposed to have her back — she demands answers. Jake explains that their boss, Nelson, never gave him the backup assignment.

When Nelson sends Jake on a similar Bratva mission, suspicion turns to certainty – Nelson is dirty. Secretly, Jake recruits Livvy as backup, and together they uncover a deadly plot — one that marks them both for death.

With danger closing in, can they expose Nelson before he silences them? And will they risk their hearts before it's too late?
