When Ryan tells Nikita an undercover agent has been arrested and they need to extract her from prison, Nikita questions why Division is continuing to run Percy's old missions. Nikita, Michael and Sean attempt to stop a terrorist attack but are one man down after Alex is shot. Meanwhile, Birkhoff and Sonia continue to bicker.
When she was a deeply troubled teenager, Nikita was rescued from death row by a secret U.S. agency known only as Division, who faked her execution and told her she was being given a second chance to start a new life and serve her country. What they didn't tell her was that she was being trained as a spy and assassin. Throughout her grueling training at Division, Nikita never lost her humanity, even falling in love with a civilian.
When her fiance was murdered, Nikita realized she had been betrayed and her dreams shattered by the only people she thought she could trust, so she did what no one else before her had been able to do: she escaped. Now, after three years in hiding, Nikita is seeking retribution and making it clear to her former bosses that she will stop at nothing to expose and destroy their covert operation.
