Go on another journey with Scarlett and Ivan as they attempt to rescue his sister from Ivan's former boss, and Norwegian crime lord, Kieran "the Punisher." With the help of Scarlett's associates and some high-tech weapons, they embark on a mission across Europe that could be their last.

Meanwhile, Scarlett continues to receive phone calls from DEA agent, Aiden Bradley, and CIA supervisor, Collin Kincaid, begging her to come back to the force. When she receives word of a posing threat in the United States, will she go home and help fight, or will she still be fighting for her own life—and the dark life that continues to beckon her?
