Nikita and Michael investigate an old corrupt Division program called P9 that appears to have resurfaced. During their investigation, they run into Owen, who informs them that he is searching for Dr. Joseph Mars, the man who not only masterminded P9, but also invented the Regimen and could help Owen wean himself off the dangerous drug.
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.
