"Unplugged" is the sixth episode of Thunderbirds Are Go!, and was broadcast on Saturday May 2nd 2015.


The episode opens with Thunderbird 2, with Virgil and Grandma Tracy on board, lifting off from Tracy Island for London. As it approaches Lady Penelope's rendezvous point, the ship’s systems shut down along with all the power in London below. Virgil is forced to make an incredibly violent emergency landing at a side street. As they disembark, Virgil guesses that it was a sustained EMF (electromagnetic frequency) generator knocking out electrical power before they hear a woman cry for help from a nearby crane. Virgil climbs to the top and tries to get the woman out but to no avail due to the door’s electronic controls. He asks her to release the crane's load but she explains that he has to do it manually by climbing across the boom and down to the coupling. Virgil manages to drop the load by giving the coupling an "old fashioned whack" from his ion wrench. The crane starts to fall but Virgil manages to jump to the coupling of another crane before the other one crashes to the ground. As he lowers himself onto the road, he admits that life in 2060 wasn’t equipped without electricity and why he can’t stop any of the power loss. After Grandma comforts him, they find a strange poster made of real old fashioned paper.

Meanwhile, Lady Penelope and Parker find the same paper, which Parker hasn't seen since his school days and Penelope reads the message "We the Luddites demand a world without technology, a world without power. We will return to the better ways of the past." They discover two Luddites and manage to knock them out and steal their hoods and masks before another Luddite says that they got to meet up with his comrades. Back at Thunderbird 2's crash site, Virgil thinks that the Luddites' EMF is near the center of London. Grandma says that they should use her map and compass, due to its magnetic affection by the EMF. Elsewhere, Parker thinks the Luddites did the "Old Lights Out Trick", a trick from his misspent youth: If there was a high tech lock the Luddites couldn’t crack they cut the power and shut down the security system.

When Virgil and Grandma follow the compass to a dead end alley, they take the London Underground. Virgil takes out a glow stick which works on a chemical reaction before his stomach rumbles. Grandma thinks she brought one of her cookies but Virgil objects her advice. After she says that the London Underground is the oldest subway system, she explains that her compass belonged to Virgil's grandpa, who had old fashioned determination and heroism. After they discover some Luddites, Virgil's stomach rumbles again but the Luddites think it was a rat before they move on. Grandma and Virgil find the EMF generator before Grandma worries about the Luddites near it.

Parker and Lady Penelope meet up with the rest of the Luddites and Penelope explains that this is the Codex Vault, a location her father brought her once. The vault is where they keep the Universal Grid Codex, a code that gives its user control of the world's power, and the Luddites want to use it to create a worldwide blackout. It turns out the Luddites are led by the Hood. They manage to open the vault and retrieve the Codex but the Hood betrays them: he intends to use the Codex to keep the lights on for a very steep price. Grandma manages to lure the Luddites guarding the EMF away from it before Virgil whacks it, causing it to crash to the floor and restoring power to London. As the vault door closes, the Hood uses a device to blind the Luddites before he escapes, pursued by Lady Penelope before the door shuts.

Virgil and Grandma rush back to Thunderbird 2 and retrieve Virgil's power suit as the Hood’s ship takes off. Virgil decides to save the crane operator rather than go after the Hood and retrieves her with his suit and they escape before the collapsed structure crashes onto the road. Back at the Codex vault, Lady Penelope contacts the Prime Minister to open the vault. When the vault is opened and the Luddites are arrested, Parker reveals that he switched the Codex for a flashlight when the Hood escaped, another trick from his misspent youth. Back at Creighton Ward Manor, Penelope congratulates Grandma and Virgil but Grandma says that she can actually congratulate Virgil. She offers him her compass and says that in a time of crisis, he can look at it and it will remind him which way to go. When Virgil says he doesn't know what to say, Grandma says to wait until his mouth isn’t full referring to one time when she was proud and he spat cookie crumbs over the couch.

Virgil: "And without a mark on Thunderbird 2!"
(A bird makes a mess on Thunderbird 2)
Grandma Tracy: "Well, almost without a mark."

Virgil: "If you've got any more words of wisdom, I could use some. How am I supposed to open the coupling when my tools aren't working?"
Grandma Tracy: "I don't know! Try giving it a good old-fashioned whack!"
Virgil: "Oh yeah, that'll work."

Grandma Tracy: "That's weird. The compass isn't pointing north. Never had any problem with it, and, a compass doesn't need power, so it can't be that OMG, can it?"
Virgil: "EMF."

Virgil: "Voila! Thunderbirds are glow!"
Grandma Tracy: "How did you do that?"
Virgil: "I just changed go to glow, and..."
Grandma Tracy: "No, not that." (referring to Virgil's light stick) "That."

Virgil: "Well, look at this place. It's like we've gone back in time, you know, to the Dark Ages? Right?"

Virgil: "I don't know what to say."
Grandma Tracy: "Then why don't you wait until your mouth isn't full? We're in tea with the Lady. Didn't I teach you anything? Here I was, saying how proud I was, and you spit cookie crumbs all over the couch?"
