After losing his life savings to Percy via a plan gone wrong, Birkhoff hacks into an old network which trips a trap set by the FBI.

Percy threatens to set off a nuclear explosion unless his demands are met. Nikita realizes the best way to stop Percy is to go into the belly of the beast: Division itself.

Nikita and Michael invade Division in an attempt to capture Percy, and Alex and Sean get caught in a deadly gunfire battle with the U.S. Marines.

A frustrated Nikita takes Alex on the road to exact revenge and, ultimately, makes a shocking decision.

Michael questions Nikita's commitment to a life beyond Division's web -- and he's not the only one with doubts.

Just as Nikita is finally starting to see an end to the long war with the Shop, Ryan confesses a secret that could unravel it all.
