Percy (Xander Berkeley) calls the President the United States (guest star Cameron Daddo) and threatens to set off a nuclear explosion unless his demands are met. Birkhoff (Aaron Stanford) finds two scientists who could help stop Percy's new nuclear satellite, so Nikita (Maggie Q) and Michael (Shane West) head after one and Sean (Dillon Casey) and Alex (Lyndsy Fonseca) look for the other. Unfortunately, Alex and Sean get caught at the very location that Percy blows up as an example of his power. Meanwhile, Nikita realizes the best way to stop Percy is to go into the belly of the beast - Division itself.
