The first two episodes of the fourth season of USA Network's spy series "La Femme Nikita" arrive Sunday at 9.
In the series, a squad of black-clad agents work for Section One, combatting terrorism by using every high-tech gadget they can get their hands on. And the secret weapon of the group is the tough, buff and beautiful Nikita -- played by Peta Wilson -- who has sacrificed a normal life to carry out these covert duties because she was wrongly convicted of a heinous crime and given a new identity in exchange for her life.
At the end of season three, Nikita and Michael, having fallen in love, planned a coup against their bosses at Section One. But this was discovered and Nikita was brainwashed by her superiors. Sunday, we find out if Nikita has become an emotionless killing machine, while Michael starts an investigation into how he can undo what was done to her.
