Section One is assigned to protect Jovan Mijovich, a politician attempting to negotiate peace among opposing forces in his section of the world. When Nikita meets with a contact to find out who has attempted to assassinate Mijovich, Nikita is recognized by Julie, a childhood friend. Nikita attempts to protect Julie's life by creating a new identity for her, but Julie is actually an operative for the organization attempting to assassinate Mijovich.

A nuclear trigger is stolen by a cold-blooded terrorist couple responsible for killing an entire team of Section One operatives. In an attempt to retrieve the trigger, Nikita poses as the wife, Helen's long-lost daughter, who was put up for adoption because Helen was in prison at the time of her birth. However, this leads to unexpected consequences for both "mother" and "daughter."
