Prisoner of the Judoon (TV story)

Prisoner of the Judoon was the first story in the third series of The Sarah Jane Adventures. It marked the first appearance of the Judoon in a spin-off and the introduction of a new species, the Veil.

Synopsis
Sarah Jane and the gang face the most dangerous day of their lives as the rhino-like Judoon return. When prisoner Androvax the Annihilator crash-lands on Earth, the Veil is set free to turn Earth's technology against itself. His next intended victim is Sarah Jane. As the Judoon fleet approaches Earth, it's a race against time to stop Androvax. With Genetec's technology on the rampage and Rani's parents taken prisoner, can anything stop the Army of the Infinitesimal?

Part 1
Sarah Jane Smith gives an overview of her life and tells how life on Earth is just as exciting as travelling the stars. She goes to interview Mr. Yorke, the head of Genetec Systems, about nanoforms and the threat they might pose if released into the environment along with the fact he is centuries away from proper programming to back his boasts. Yorke takes her questions poorly and has her thrown out. Sarah Jane takes it in stride.

She returns home to find Luke and Clyde playing football. Rani comes over just as a "meteor" crashes onto the Earth. They race inside and Sarah Jane activates Mr Smith, who tells them that the falling object crossed the solar system in forty-five minutes. Sarah Jane says it can't be a meteor. Mr Smith notes the falling object sent a distress signal. His monitor shows Judoon calling for help. He says a life-pod was launched before the ship crashed. Sarah Jane explains the Judoon's job and their dimwitted methods. Mr Smith says UNIT has secured the area. Worried that UNIT will get into a fight with the Judoon, Sarah Jane tells her companions that it's time to move out. As they leave, Gita (once again) causes a delay by asking Sarah Jane if any of her contacts would be interested in her flower shop, "Bloomin' Lovely". Sarah Jane distractedly gives Gita a brochure from Genetec Systems. Gita decides to fill the company's office with plants as a sort of guerrilla marketing and drags Haresh with her.

They soon find the Judoon pilot pursuing his now-escaped prisoner and are nearly hit by stray blast from his weapon. Sarah Jane explains that under the rules of the Shadow Proclamation, Earth barely exists. To make matters worse, the Judoon are brutal and will execute anyone that gets in their way.

In the meantime, the Judoon is knocked out by the escapee with a board, allowing him time to escape his straitjacket and flee. Sarah Jane and the others find the Judoon and move his blaster away. The Judoon awakens, takes out its "language assimilation/cataloguing device" and records Sarah Jane's offering of help and warning not to harm them. Assimilating English, the Judoon says his name is Captain Tybo and his prisoner, Androvax, is the "Destroyer of Worlds".

To prevent Tybo from harming any innocent humans in his zeal to recapture Androvax, Sarah Jane insists on helping his investigations. After hearing a young girl's scream nearby, Sarah Jane and Clyde run to investigate, leaving Luke and Rani to keep Tybo distracted.

They find the girl. They attempt to comfort her and find out where her mother is. However, Sarah Jane's watch begins to beep. She had been scanning the girl, who is not human. Androvax steps out of the girl's body and into Sarah Jane's, then puts Clyde in a trance.

Captain Tybo figures out that Luke and Rani are distracting him. He smashes their cellphones to prevent any more mistakes. He says Androvax is a Veil life form, capable of possessing others. They find Clyde in the theatre, revive him with a squirt bottle after slapping him proves ineffective, and learn Androvax has Sarah Jane.

Tybo "commandeers" a police car and they pursue Sarah Jane/Androvax back to Bannerman Road, where she has been talking to Mr Smith. Sarah Jane returns to Genetec Systems, where she talked to Mr York about the nanoforms. Captain Tybo, Rani, Luke and Clyde reach the attic only to discover that Mr Smith has been set to self-destruct in sixty seconds, which will destroy all of Bannerman Road.

Part 2
Captain Tybo is prepared to blast Mr Smith, but Luke stops the countdown by telling Mr Smith that exploding would contradict his purpose of defending and protecting Earth, as the resulting explosion would destroy several city blocks. Mr Smith tells Luke, Rani, Tybo and Clyde where Sarah Jane is — Genetec System Labs. Androvax plans to use the nanoforms to build a spaceship for escape, then allow them to run wild and destroy the Earth. Meanwhile, Gita and Haresh have been arrested by the security guard there, but when Androvax sets off multiple alarms, the guard leaves and they escape. Luke, Rani and Clyde arrive with Tybo. Rani insists they hide when she sees her parents roaming the building. The kids decide to lock the Judoon Captain in a shielded room to prevent him harming Sarah Jane in his zeal to stop Androvax.

More Judoon arrive on the scene, right behind Haresh and Gita. Haresh wants to find out what they're up to, but Gita is more concerned about finding the security guard, who's taken her mobile, and staying alive. The Judoon comment that Gita is more intellegent than Haresh; interfering with their work will warrant termination. In the meantime, Sarah Jane argues with Androvax, but when the kids arrive in the lab, Androvax captures Luke and sets the nanoforms after Clyde and Rani with Sarah Jane's sonic lipstick. They recall that nanoforms will go dormant at low temperatures and defeat them with a fire extinguisher.

Androvax takes Luke aboard the now-complete space ship. Sarah Jane attempts to take control of her body again. Clyde and Rani also appear and Luke steals the ship's power core, insisting they'll let Androvax escape if he releases Sarah Jane. Androvax finally agrees, but the Judoon arrive to arrest him moments later.

The nanoforms, meanwhile, have begun eating the building and Haresh and Gita are trapped inside. Luke uses the spaceship's computer to deactivate the nanoforms. The Judoon leave with their prisoner in the ship. Tybo, taking into account the youngsters' part in stopping Androvax, chooses not to prosecute them for locking him in the room. Instead, he revokes their interplanetary travel rights — oddly as Earthlings shouldn't have any — effectively "grounding" them on Earth. Sarah Jane and her team arrive home safe, where Gita and Haresh regale them with the harrowing story of their encounter with aliens.

Story notes

 * Beginning with this episode, Sarah Jane episodes now begin with a brief prologue in which Clyde breaks the fourth wall to explain the characters and concept of the series to viewers. This same footage had previously formed the basis of the cinema trailer for the season. This teaser includes brief scenes from the different stories of the season. This opening was also used in Series 4 and Series 5 (with the preview footage updated appropriately).
 * Nicholas Briggs, who performs the Judoon's voice, has now been credited on all three Doctor Who-franchise series.
 * This marks the sixth appearance for the Judoon. The others were in TV: Smith and Jones, TV: The Stolen Earth, PROSE: Revenge of the Judoon, PROSE: Judgement of the Judoon and the Fifth Doctor flashback in COMIC: The Forgotten
 * This marks the third story to feature Judoon at the end of the title. The others are Revenge of the Judoon and Judgement of the Judoon.
 * This is Nicholas Briggs' only appearance in The Sarah Jane Adventures.
 * Mr Smith mentions a spaceship crash in Roswell, New Mexico in 1947 and the Dreamland base in Arizona. This is the first time that plotlines for future episodes have been pre-referenced (at least with the production team's knowledge of future use), as Roswell and Dreamland were involved in a future animated serial titled Dreamland that, at the time this episode was broadcast, was in late production stages.

Continuity

 * The ship that Androvax ordered the nano-bugs to create was based on the schematics of a crashed ship re-engineered at the Dreamland base in Arizona. The original ship had crashed in Roswell, New Mexico in 1947. The completed ship is identical to the one seen in the Doctor Who story TV: Dreamland.
 * Captain Tybo refers to Androvax as the Destroyer of Worlds, the Tenth Doctor was also called this by Davros in TV: Journey's End.
 * Androvax would escape the Judoon's prison planet and return to Earth. (TV: The Vault of Secrets)
 * Clyde and Rani's 'grounding' by the Judoon is referenced in TV: The Wedding of Sarah Jane Smith and becomes an important plot point in TV: The Empty Planet.
 * Once again, Sarah Jane bristles at being called "Sarah" by Gita, even though the Doctor will later refer to her as such in TV: The Wedding of Sarah Jane Smith; however in his case, it was an affectionate name he used toward her during his fourth incarnation.
 * Mr Smith reminds the Veil-possessed Sarah Jane he is a Xylok, indicating he has some knowledge of his alien identity intact after the virus-induced memory deletion, though none of the hostile elements remain. (TV: The Lost Boy)
 * When Mr Smith's self-detonation countdown reaches 22 seconds, his monitor begins to scramble and displays several past analyses, including the Melasaran Galaxy, planet Sontar and the probic vent of a Sontaran (TV: The Last Sontaran); the ticket for Spellman's Magical Museum of the Circus (TV: The Day of the Clown); and a Slitheen. (TV: Revenge of the Slitheen, From Raxacoricofallapatorius with Love)
 * Androvax deducts that Luke was grown from synthesised DNA as a perfect human being, he was part of an alien invasion, and he ended up as Sarah Jane's adopted son because of her meddling. (TV: Invasion of the Bane)
