Nikita (2010)

Killer-for-hire Nikita (Maggie Q) owes her life to a secret U.S. government agency called Division, but her gratitude turns to lethal bitterness when she realizes that her employers have cynically betrayed her. After years underground, Nikita emerges and initiates her plan to expose the agency's illegal covert operations. But standing in her way is a new crew of Division-trained assassins, all equally determined to protect those same secrets.
