Nikita is sent back to Section One to destroy a new terrorist threat that only she can deal with which is a summit meeting of representatives from several terrorist groups. She is teamed up with a new level 5 operative, Marco O'Brien. O'Brien was the police officer recruited four years earlier because of a mistake Nikita made, a fact that O'Brien has not forgotten. Nikita finds that besides the terrorists, she must deal with O'Brien & the hostility of much of Section personnel because of her role in Center's evaluation of Section.
