The Last Sontaran (TV story)

The Last Sontaran was the first story of the second series of The Sarah Jane Adventures. In it, Maria Jackson left the regular cast. Notably, it acted as a sequel to the Doctor Who episode, The Poison Sky, dealing with the consequences of the Tenth Doctor's battle with the Tenth Sontaran Battle Fleet.

Synopsis
Reports of strange lights around the Tycho Project's radio telescope lead Sarah Jane, Luke, Clyde and Maria into a terrifying forest encounter. Sarah Jane comes face-to-face with her oldest enemy. Meanwhile, Maria wrestles with a huge decision when her dad is offered a new job in America.

Part 1
Sarah Jane and Maria discuss the experiences they have shared since Maria's arrival in Bannerman Road. They watch the night sky as they look forward to many more discoveries.

In rural Goblin's Copse, at a radio telescope used in the Tycho Project's search for alien life, Lucy Skinner and her astronomer dad, Professor Nicholas Skinner, also watch the night sky. They spot strange lights floating about. Professor Skinner investigates, but goes missing. Lucy investigates, and is promptly captured.

The next day, Luke and Clyde play a strategy game with Mr Smith to learn about battle strategies. Sarah Jane interrupts. She had heard reports of the strange lights the previous night. Despite Mr Smith's assurances that strange lights rarely herald alien activity, she pursues the story.

Maria and Alan have received an important letter, but have found that the implications are far larger than they imagined and will cause an imminent major change in their lives. Alan tells Maria the decision is not just his to make.

Sarah Jane, Clyde, Luke and Maria head to the countryside to investigate. They arrive at Goblin's Copse and discuss the size of space. They are watched by something. Inside, the team finds Lucy, who tells them that her dad is still missing. Luke and Clyde look outside for the Professor after being warned to stay away from the woods. As the boys search the woods, the creature watching them becomes invisible.

While Lucy sleeps, Sarah Jane decides to ask Maria what is troubling her after noticing some unusual behaviour and Maria reveals that Alan has been offered a job in America, at the head office of his firm. Maria is ambivalent about the news; she is happy for her dad but sad that she must leave her friends behind. Sarah Jane closes herself off from Maria, telling her she's happy for her but is clearly upset.

At his house, Alan discusses the job with Chrissie and how it will change Maria's life more than his.

In the woods, Clyde and Luke hear a noise. A Sontaran, armed with a gun, reveals himself and chases them. The boys lose him, but come across a cloaked object.

When Lucy wakes up, Sarah Jane persuades her to recall the events of the previous night. Professor Skinner appears, though he seems strangely detached and unemotional. He orders Sarah Jane and Maria to leave immediately, which they do. Lucy makes him some coffee and he approaches her strangely.

Luke calls Sarah Jane and when she and Maria arrive, Clyde and he show them the object. When the cloaking field is disabled, Sarah Jane immediately recognises the Sontaran ship. Its Sontaran occupant, Commander Kaagh, appears behind them, armed.

Maria tricks Kaagh and the group escape, splitting up, with Kaagh chasing them. Sarah Jane and Clyde attempt to reason with Professor Skinner. They find his mind is controlled by the Sontaran. Outside the Observatory, Luke and Maria crawl into a vent that leads into the building.

Maria and Luke watch from the vent while Kaagh and Sarah Jane talk. He says he was badly wounded when the Tenth Doctor defeated the Sontaran army. As the only survivor of the botched invasion, he has vowed revenge on Earth for his peoples' humiliation. He reveals his plan to use the Tycho radio telescope to take control of Earth's satellites, and steer them to crash into nuclear stockpiles on Earth, triggering nuclear annihilation.

Clyde protests, so Kaagh says he will experiment on him. Sarah Jane steps in front of Clyde, defying Kaagh. He pulls out his gun and shoots her.

Part 2
Kaagh shoots Sarah Jane. She sprawls unconscious on the floor. He boasts to Clyde she will be taken to Sontar as a prize and he will be hailed as a hero instead of a laughingstock. Perhaps he will be given a more honourable epithet, like "Kaagh the Avenger".

Luke and Maria, hidden in a nearby vent, watch the scene unfold. They catch Clyde's attention and motion for him to join them.

Sarah Jane awakens to find she is in a store room with Lucy Skinner. Kaagh has taken her sonic lipstick. Undeterred, Lucy and she start to build a device to jam the satellite. Aware that Kaagh will detect it, they plan to escape when he comes to investigate.

Luke, Maria and Clyde provoke Kaagh into chasing them through the observatory's corridors and service tunnels. The teens escape into the forest and block Kaagh's exit. They run to his shuttle, where Luke uses the chemicals stored there to synthesise a knockout gas to incapacitate the Sontaran. He sets off the intruder alarm. Knowing it will bring Kaagh, Clyde goes to distract him. As Luke works, Maria tells him about the upcoming move which leaves him upset, but Maria reminds him it won't matter if Kaagh succeeds. Sarah Jane activates her new invention; just as she expected, Skinner come to find it. Sarah Jane and Lucy sneak out, locking Skinner in the room, and try to figure out how to disarm the satellites. They let Clyde in by the same door Luke, Maria and Clyde escaped through earlier, just in time to save him from Kaagh, whom they lock out. Kaagh enters through the main door, breaks down the door to the room Skinner was locked in and rages at him.

Maria, uncertain Luke will synthesise the gas in time, decides to ask Mr Smith for more information on defeating Sontarans. As Mr Smith is still in Ealing, she calls her dad and asks him to contact the computer. Alan does so, unaware he has been followed into Sarah Jane's attic by his ex-wife, Chrissie. She demands to know what is going on; Alan quickly brings her up to speed on Sarah Jane's alien hunting and Maria's role as her assistant. Chrissie realises he is telling the truth because his lip twitches when he is lying. Maria's parents, fearful for her safety, decide to join their daughter at Goblin's Copse.

Sarah Jane, Maria, Clyde, Luke and Lucy all meet up. Sarah Jane takes Luke and Lucy with her to try to deactivate the transmitter, while Maria and Clyde search for the switch that will move the transmitter away from the satellites. However, Kaagh and Skinner get there first and capture them.

Luke tries to break into the observatory's main computers, succeeding when he realises that Sontarans, who have three fingers on each hand, use base six mathematics. Kaagh appears and reveals Lucy is a sleeper agent. He activates the mind-control chip implanted in her. He orders her to re-activate the transmitter. He threatened Maria's life if Sarah Jane tries to stop him. All appears lost -- until Chrissie bursts into the observatory and attacks Kaagh's probic vent with her high-heeled shoe, incapacitating him more effectively than Luke's knockout gas did. The transmitter is deactivated, this time for good. Kaagh is escorted back to his ship and ordered to return to Sontar, which he is only too glad to do; he is humiliated that he was defeated by "half-forms" (children) and a woman. Sarah Jane is relieved, even if she is not entirely convinced that the Sontaran is gone for good.

Six weeks later, Maria and Alan say their goodbyes to Sarah Jane, Luke and Clyde as they leave for their new life in America. As father and daughter pull away, Chrissie whispers to Sarah Jane that she was not entirely ignorant of her daughter's alien-hunting hobby.

Story notes

 * This is Maria Jackson's last story as a main character. Actress Yasmin Paige was in her GCSE year and chose to concentrate on her studies. She made a guest appearance in part 2 of The Mark of the Berserker and Maria is referenced either visually (through photos, art and flashbacks) or in dialogue in all other Season 2 stories.
 * Although this story clearly takes place after the Sontaran Stratagem/Poison Sky story, it is unclear whether it takes place after the events of TV: The Stolen Earth/Journey's End, which aired before it. The episode contains dialogue references to alien life being widely known on Earth. The reference to Maria in The Stolen Earth would suggest it took place before Maria and her father moved to America.
 * This story marks the final appearance of Chrissie Jackson on the series.

Production errors

 * About thirteen minutes into Part Two, a shot of the countdown is shown as a video playing in VLC Media Play.

Continuity

 * The Tycho Project is mentioned in PROSE: Beautiful Chaos.
 * Sarah Jane refers to her two earlier encounters with Sontarans: one a long time ago (TV: The Time Warrior) and one in the future. (TV: The Sontaran Experiment) She tells Kaagh that the Sontaran empire will still exist thousands of years in the future and will still be at war with the Rutan Host.
 * Kaagh is a survivor of the Sontaran invasion. He was on his way to Earth when the spaceship was destroyed by the Tenth Doctor and his ship crashed on Earth. (TV:The Sontaran Stratagem/The Poison Sky)
 * As Chrissie breaks into Sarah Jane's house she notes, "Some people never learn." She earlier broke into Sarah Jane's house through the same window. (TV: Eye of the Gorgon)
 * Chrissie called Sarah Jane many names throughout the first series. (TV: Invasion of the Bane, et. al.) In this episode she calls her Calamity Jane.
 * Clyde initially remarks that Kaagh looks like a spud. This is part of an ongoing joke comparing the appearance of Sontarans to potatoes. (TV: Eye of the Gorgon, et. al.)
