Benson is still trying to get used to having guardianship over Calvin while his mother's on the lam. On top of adjusting to her new responsibility, she also gets a surprise late-night visit from undercover agent Dana Lewis, who has a special request. She gives Benson a rape kit to run. When Benson asks who the Jane Doe rape kit belongs to, Dana says it's hers.
Benson tells Stabler about Dana's case. They can't reveal Dana's identity during their investigation out of fear her cover will be blown. The two head over to Dana's New York apartment where she was raped. Dana goes over her story of being attacked and says she was injected with a drug that causes temporary paralysis. After Dana tells her story, she agrees to cooperate more with the rape investigation, as long as it doesn't affect her undercover work.
Benson and Stabler tag behind Dana to an anti-mosque rally. In the midst of the chaos, she's kidnapped by a group of men in a van. Stabler radios a call to track the van down. When they find it, it's on fire, and the driver's been shot in the head. All the other passengers seemed to have vanished, including Dana. Back at the FBI, Stabler and Benson are shocked to hear Dana left the FBI a year ago.
The passengers and murdered van driver all belonged to an anti-government militia. When the detectives hear about a militia raid in the city, they go to investigate, and are shocked to find Dana there. Her boss didn't want to blow her cover, so he lied to the detectives about her quitting the FBI. Dana tells the detectives that she was about to close her case, but when the cops called in her kidnapping, the militia panicked, shooting the driver and burning the car. That's when they all ended up back in the city, and a shoot-out began. All the other van passengers were killed except for Dana.
Fin and Munch discover another rape similar to Dana's took place in Soho. Similar except that the other victim didn't survive the much more brutal attack. Benson and Stabler go back to Dana's FBI office and tell her they need her complete cooperation in their investigation. The young victim worked in the jewelry district, and Dana says the FBI had been investigating another case involving stolen gems.
The detectives discover the second victim belonged to a prison pen pal program, which put her in contact with a violent criminal who also fits the description of Dana's attacker. But Seth Coleman has no connection to any militias. Stabler gets Coleman's new address from his parole officer and he and Benson head over to question him. The detectives find that Dana has trailed them. Benson reminds Dana that she can't be involved in her own rape investigation.
Coleman spots Stabler and Benson outside his apartment and makes a run for it. Dana gets back on her motorcycle and chases him down. Benson and Stabler trace them to a construction site, where Dana has her gun aimed at Coleman and he has a nail gun aimed at her. Dana taunts Coleman as the detectives watch and tell her to back off. Coleman puts the nail gun down, but Dana continues to train her weapon on him.
Dana lets her emotions get the best of her and shoots at Coleman. The bullet ricochets off a beam and nicks Stabler in the shoulder. While at the hospital, Dana apologizes to Stabler for the shooting. She's been suspended from work and lost her gun privileges. Back in the interrogation room, Coleman continues to deny raping Dana, but he does confess to raping and murdering Jennifer, the second victim.
When Dana learns that Coleman refused to admit he raped her, she pays him a visit in prison. He continues to deny raping her and calls for the guard. Dana keeps asking him, "Why me?" Benson drags her away from Coleman's cell. The next day, Dana is called to testify at Coleman's trial. Coleman's defense attorney keeps bringing up Dana's reckless actions against his client, including trying to shoot him.
After Coleman's defense attorney begins to question whether Dana was ever really raped, ADA Hardwicke redirects Dana's testimony, asking for more details. Dana reluctantly tells the jury things Coleman said to her during her rape. She also describes all the ways he violated her while she was temporarily paralyzed.
Benson listens to Dana's emotional testimony about her ordeal, and something clicks when Dana says her attacker called her a "star." The Judge orders a 10-minute recess so Dana can regroup. Benson points out that Dana's FBI alias was "Star" when she investigated a neo-Nazi militia four years ago. Coleman joined an Aryan group while in prison that was run by the man Dana put away, Brian Ackerman.
Benson, Stabler and Dana visit Ackerman in prison. Dana accuses him of sending Coleman after her to get revenge, since she killed his son during a raid four years earlier. Ackerman confesses to sending Coleman after Dana. Ackerman takes joy in knowing the pain Coleman caused her. Dana tells Ackerman that she has a husband and two beautiful children to watch grow up; that's something he'll never have.
