About me: Fox's father was a district attorney. He was prosecuting a mob boss but the defendant wanted a softer judge. So they hired an assassin named Max Petridge to "pay him a visit." Doing so meant he broke in, tied up Fox and her father, and made Fox watch while he burned her father alive. After which, he took a wire hanger and branded his initials into the right side of Fox's neck, so she would never forget. It is unknown how she got recruited into The Fraternity, but Fox later found out Petridge's name came up, weeks before her father was killed, and a Fraternity member failed to pull the trigger.
One day she gets a mission to recruit Wesley Gibson. She tells him he was the son of the greatest assassin who ever lived and that the man who killed him was an assassin called Cross. Cross appears at the pharmacy and Fox and him have a shootout. After a vicious car chase shootout with Cross, she takes Wesley to the Fraternity headquarters, where Sloan explains that Wesley is destined to join the Fraternity. Unbelieving, Wesley leaves.

The next day, Wesley tells off his boss and hits his best friend in the face with a keyboard (which in slow motion has keys pop out of it to read "FUCK YOU" with a tooth for the second "U") for constantly having sex with his girlfriend. Fox meets with him outside of the office building and takes him to the Chicago Fraternity's headquarters. After weeks of training, Wesley goes back to his old apartment to retrieve his father's Flyswatter Beretta 92. He finds his best friend there and breaks the door open, knocking him down, and is screamed at by his girlfriend. Fox hears her yelling at him, thinks for a second, smiles, and enters the apartment, just as Wesley is exiting. His girlfriend demands who she is, but Fox ignores her and kisses him, although it's unknown if she did this to reveal that she loves him, just to screw with his girlfriend, or maybe a bit of both. Whatever the reason, they left the apartment with his girlfriend shocked and his best friend amused, saying that Wesley is "the man." They then come out of the building where she tells him to stay while she goes to steal a car for them. Wesley notices that Cross is across the street and pursues him. Thinking it is Cross, Wesley mistakenly kills The Russian, a fellow Fraternity member. Wesley is then shot by Cross in the shoulder. Wesley is taken to the recovery room at the Fraternity and the Russian dies, while Fox attempts to save his life with CPR.
Wesley traces the bullet Cross shot him with to an ammunition manufacturer named Pekwarsky. Fox is then given her next assignment: Wesley. She goes with Wesley and captures the maker of the bullet and forces him to lure Cross to a meeting at the local train station. Pekwarsky flees. Wesley realizes Cross is on the train. Wesley pursues Cross, but Fox follows Pekwarsky too far to catch up with Wesley after she realizes they are split up. Fox steals a car and follows the train, gaining entrance by crashing the car into the side of the train. Wesley and Cross have a shootout, but the train falls off its tracks atop a canyon, and Cross saves Wesley from falling. Wesley shoots him regardless, and in his last words, Cross tells him that Wesley is his son. Fox explains to him why the Fraternity lied about Wesley's father, telling him Wesley is the only one Cross wouldn't kill. She also reveals that Cross's name came up, as did Wesley's, but just when she is about to fulfill the kill for Her car slams into her head and knocks her unconscious. Later, she woke up and tried to climb out of the train but fell and passed out. Wesley, Wesley shoots the glass, falling into a river below in the canyon with his father's corpse.
