Complete story — includes the ending
Robbie returns and steals three 20-year-old motherboards relevant to Project Crossbow, a missile defense satellite, from an Air Force base. Nikita and her entourage find the only remaining member of Crossbow, Donald Henderson. However, he dies after Nikita and Michael stop a Division strike team. Birkhoff later realizes that Crossbow is a satellite that can fire a particle beam. Sean and Alex find Robbie at a nuclear reactor and capture him. However, he escapes and activates a device before Sean kills him. They believe that the device sends the satellite to fire the weapon at the facility and escape before it explodes. Percy uses the weapon as leverage to blackmail President Charles Grayson into backing out of a peace treaty between Afghanistan and the Taliban. Nikita decides to return to Division. While Sean and Alex subdue the sentries (they must be kept alive, otherwise Division is alerted of a breach), Nikita and Michael enter Division through the hatch Nikita previously escaped through. One of the sentries kills the other, alerting Division of Nikita's presence, just as she destroys the servers controlling Crossbow.
