The main characters are Maggie Q as Nikita, Shane West as Michael, Lyndsy Fonseca as Alex, Aaron Stanford as Birkhoff, Melinda Clarke as Amanda and Xander Berkeley as Percy.
At the beginning of every episode, Nikita provides the viewers a brief synopsis of what this is all about. Nikita was the first to escape Division but she won’t be the last. After killing a police officer who shot her friend during an altercation and tried to cover it up, Nikita, drunk and high on drug, managed to retrieve a pistol and shot the officer. She was sentenced to death. Division, the rogue organization that’s accountable to no one, seeks those very types of individuals, train them and turn them into “legitimate” criminals. Only this time, they get to kill for their country, so they thought. In reality, all assassinations they carried out were to advance Percy’s agenda. They staged her execution, gave her new identity and trained her to become an assassin. Division exclusively recruits the worst of society; so it’s safe to assume that everyone at Division has a dark past.
Alex was the only one who survived a murder assassination of her family, courtesy of Nikita. Incidentally, Nikita was tasked to erase the whole family. She went off script and saved Alex. That didn’t do her much good. Alex was sold as slave prostitute to an underworld market. Alex was always high. She’d do anything to get a joint. When Nikita came out in the open, her first mission was to find Alex. She did. Nikita felt responsible for her, for what happened to her family. After a rough start, they became friends. Alex proposed to join Division to help Nikita stay a step ahead of its activities. So, Alex joined Division. Fortunately, Division had a blindspot, Percy had no idea that Alex is Alexandra Udinov, the daughter of Nikolai Udinov, the family he ordered Nikita to erase from the face of the earth. After Alex joins Division, she would find out that the organization was responsible for his parents’ murder. It would be a while before she became aware that Nikita was the one who pulled the trigger.
