Arianna Jackson had worked for Guardians Inc. for 4 years after returning home from military duty because the guy she had been dating had tried to frame her for giving intel to the enemy in the Middle East. Her work there led her to accept the job with the female bodyguard organization. She didn't want anyone to have to live as frightened as she was during the time she was being watched. Her assignment had been Esther Perkins. She was divorcing her husband, Thomas, who was part of a huge crime syndicate in Alaska. He didn't show up for the hearing and they returned home to find him tied up in Esther's library while Joseph Rainwater, head of the syndicate, held a gun to his head. Arianna witnessed him shoot Thomas in the head and she was now in the Witness Protection program.
Kevin Laird, Mark Baylor and Body Callahan were the deputy US Marshall's assigned to guard Arianna. Brody arrived and told Arianna that Esther was missing. He would let her know if she was found. They didn't know if she was dead or alive but they were worried because they found her blood where she was taken.
The night they arrived, Arianna woke up when she heard the sound of a gun with a silencer go off. She got up and she and Brody snuck out of their rooms with guns. Arianna shot one guy in the kitchen while Brody shot the other. Brody went outside, fought and killed another guy. They saw Mark was dead but couldn't locate Kevin. They didn't know if he was dead or if he had led the guys to the cabin. Brody packed up food and camping items while Arianna took pictures of the victims so they could identify them later and they left the cabin.
They headed out into the woods and soon heard something behind them. They looked from a high spot and saw that someone had started what appeared to be a forest fire. They first had to scare off a grizzly bear. Their next feat was crossing a river. Arianna was deathly afraid of rushing water because she had lost her sister in a flood when she was younger. She sucked it up and Brody tied a rope to her but she slipped and was washed downstream a bit. She made it across though after Brody helped her out. Next came the rappelling down a mountainside. Brody slipped and took a pretty good fall. He sprained or broke an ankle and got a gash on the back of his head. Brody slept for a couple of hours and then they continued toward Fairbanks. It was the next day before they noticed a campsite. The campers tied them up and went to find the state troopers. They returned quickly after looking through Brody's wallet and noticing the US Marshall badge. They untied Brody and Arianna and drove them into Fairbanks. Brody called a friend who had recently retired to come pick them up. They stopped to pick up some food when Brody saw another Marshall get out of a car nearby. It was Carla, a woman that he had dated a couple of times. He didn't know if she was there as a Marshall or as one of Rainwater's lackey's.
Charlie picked them up and took them to the cabin of a neighbor. He called the neighbor's sister, Willow, and told her that he would accept an offer to help her transport a couple of her horses to Anchorage. Brody kissed Arianna before he went to sleep that night. Arianna was awake as guard while the guys slept and she smelled smoke. She woke up the guys and told Charlie that she thought his place was on fire. Charlie left to stealthily check it out and she was right. They used his friends old truck and drove early to Willow's place to pick up the horses. They stopped to get gas and suspected that they were seen. They were waved down by a black SUV that had gotten gas while at the same station they stopped at. They t-boned the SUV and killed 2 of the guys who where trying to kill them. One was killed by the accident. They tied up one guy and a woman. Charlie called a state trooper friend who took them to an airport to get a ride to Seward. They arrived and a car was waiting for them to drive the rest of the way. They stopped to pick up some makeup and clothes that Arianna used to disguise them as older than they actually were. She knew what she was doing from working behind the scenes of stage productions during high school and college.
Brody tried to prevent himself from getting too involved with Arianna and Arianna was also fighting against her growing attraction to Brody. She knew that she was going to have to leave everyone and everything behind and go into the WitSec program. Brody told her that he wouldn't ever give up his life and family. A relationship between the two of them was doomed.
Charlie drove them into Anchorage after being held up by an 18 wheeler accident that looked to be intentional and seeing another car stopped on the roadside on the way in. That car had looked as if they were watching people passing by.
They broke in and stayed at the home of a Marshall who was on vacation. Charlie was good with computers and did some searching of other Marshall's on the case to see if they could find out who the mole was. They were betting on it being Mark, he was badly in debt that he had recently paid off but they still weren't sure.
Brody went to the prosecutors house and told him that Arianna was in town. He was sneaking back out from his place when two of Rainwater's assassins caught up with him. They took him inside and started beating him to find out where Arianna was being held.
Arianna, Charlie, Gus (a trooper friend) and Gus's cousin were in a van dressed as phone workers and heading to the courthouse. Arianna said she wasn't leaving without Brody and went to the prosecutor's house to see what was holding him up. They broke into his house and surprised the assassins. They tied them up while holding guns on them and took Brody with them. They would call the police to come pick them up later. They went to the courthouse and Arianna gave her testimony against Rainwater. They were leaving the courthouse when a police officer in the hall pulled out his gun to shoot Arianna. Brody jumped in front of the bullet.
Arianna was pulled away from Brody and told she was now in the WitSec program. She told the Marshall's that she wouldn't go with them until she saw for herself that Brody was going to be okay.
She got in the car to be taken to the hospital the next morning and was surprised to see him in the vehicle. She wanted to tell him she was in love with him but held back because she knew she had to let him go. He had been shot in the arm and was told that would would heal completely in time. One bullet had grazed his head and another had cracked a rib. Brody told her that Rainwater had been found guilty of murder and the mole had been Kevin. His brother was in the military and had recruited Kevin to help him steal military weapons for Rainwater's organization. Arianna kissed Brody on a clear area near his lips, thanked him and told him goodbye. Brody's face was still a mess from the beating he had taken from Rainwater's assassins. She felt her heart break as they parted.
Nine months later, now as Kim Wells, she was working on her horse ranch in Wyoming a strange car came up her driveway. She pulled out her rifle and waited. She was surprised to see Brody step out of the car. He told her that he was no longer happy with his job. It had taken 5 months of rehab to get him back to work. He told her that he was in love with her and all he wanted was her. He was in love with her and was willing to join her in the WitSec program if she would marry him. She told him she was still in love with him and kissed him.
