Plot summary
To prevent journalist Jill Morelli from attempting to expose a plane crash that was organized by Division, agents frame her for her editor's murder. Nikita rescues Jill, and they work together to expose the story. They contact Jill's source, who has a video in which Division agents can be seen at the site of the crash, covering up the evidence and obtaining cocaine smuggled by the airline's corrupt CEO. Michael, with tracking assistance from Alex and fellow recruits Jaden and Thom, finds the house where Nikita, Jill, and Jill's source are meeting.
Michael leads a Division team there and kills Jill's source. Alex secretly alerts police to the area, who arrest Jill while Nikita fights the Division agents. Jill manages to expose the story and clear her name. Meanwhile, Michael and Percy suspect Birkhoff is leaking information to Nikita from inside Division (unaware that the real mole is Alex). After Birkhoff is interrogated by Amanda, they discover a tracker hidden in one of his teeth; Nikita tells Alex that they will need to find another way to cover her tracks. Thom brings Alex a CD player as a reward for her tracking assistance on the operation.
