Bright and attractive, small business owner Katie Blackburn angrily relates her experience during the interview when, unknowingly, Katie gives AJ the break she’s desperately needed. Immediately, Katie presents another kind of battle for AJ. Just as she took the oath to keep America safe, AJ’s heart begins to feel the same oath for Katie. AJ knows drugs don’t care who handles them, but she does. It’s her job and her war.
