Power Down is the eighth episode of NCIS Season 7 and the 146th episode of the entire NCIS series.
An attack on SwiftCast, an Internet provider is facilitated by an explosion at Potomac electric substation which leaves Washington D.C. without any electricity also severely exposed, forcing the NCIS team to use old-school methods to investigate the death of a Naval officer.
In his house, an male Unnamed Gamer while playing a MMORPG in a scary voice states to "Grimlock the Great" that they've stolen his Magic Meteor, plundered his elderberry fields and crossed into his land for the last time before he tells the Great to meet his fate, the son of a half-gnome.
Suddenly, the computer screen cackles with static as a sign saying "Internet Connection Lost" pops up.
The Unnamed Gamer freaks out, yelling "NO!".
He then slams the SwiftCast connection box before calling for his mother who yells, "What?".
The Gamer tells her that the Internet's down again.
The Gamer then slams the connection box, wondering what the Hell is wrong now?
It then closes up on the SwiftCast internet connection box before showing that the dialogue button is flashing red.
At SwiftCast, a huge gunfight is taking place as security guard Dane Frazier attempts to stop two masked individuals.
When the two emerge, Fraizer ducks behind a wall for cover before firing off some more shots and then ducking again as the two fire back.
As this happen, the alarm wails.
Meanwhile, security guard Ryan Stone emerges from a door, ready.
As Fraizer fires off some more shots and then ducks, Stone bursts out of the door, his own gun drawn and he fires two shots as one masked individual ducks behind a wall.
Fraizer then fires off another shot while Stone hides behind a wall.
As more shots emerge, Fraizer ducks.
The second masked individual then spots a weak point and fires off another shot, the gunshot striking Stone in the right arm and sending him to the ground.
"Stone!", Fraizer calls.
Unwilling to let his colleague die, Fraizer then emerges from his hiding spot while firing off some shots, presumably as a distraction before he helps Stone to safety as the gunfight rages on.
Stone then cries out in agony, obviously in pain from being shot in the arm. He then tells Fraizer that he got the jump on one and cuffed them to a pipe.
As this goes on, Fraizer is ducking, obviously unwilling to get shot. He wonders what these guys want.
Glancing at the blood, Stone remarks that maybe they're pissed with their service.
"Where's that back-up?", Fraizer wonders.
As this goes on, the second masked individual is holding a remote which he then hits.
Outside, the lights go off, ultimately plunging the entire company into darkness and leaving Stone and Fraizer trapped.
"Now what?", Stone wonders.
It then cuts to an overhead shot of Washington D.C. which seconds later is plunged into darkness.
In the Evidence Garage, Resik explains to Gibbs and McGee that NSA had agreements with all major bio-metric security companies to program a backdoor into their iris scanners.
- The credits sequence ends with the usual Washington view and a car, but with a difference as the credits suddenly stop rather abruptly due to the power cut which hints what's going to happen in the episode.
- When Gibbs is being briefed by Ducky, you can the autopsied corpse's stomach rising up and down.
- On her fake U.S. passport, Lt. Paxton's alias "Susan Kinkirk" is misspelled "Susaan."
