Synopsis
The materialises in a corridor, and the
steps out bewildered and alone. He walks into a room, where it is
revealed that he is being put on trial for conduct unbecoming a Time
Lord. The notes that the Doctor ,
and the Valeyard states that he will argue that the Doctor was shown
too much leniency on that occasion. The Valeyard opens the case by
using the to show the Doctor's involvement on the planet Ravolox.
The Doctor and arrive on Ravolox, which is virtually identical to .
He tells Peri that the official records state that the planet was
devastated by a fireball, but they note that the forest they are
walking through suggests otherwise. They are seen by
and Dibber, who attempt to shoot the Doctor; but he moves off just in
time. Glitz and Dibber discuss their plan to destroy the "L3 robot" by
sabotaging its light conversion system, which has been turned into a by a primitive tribe on the planet.
The Doctor and Peri find an apparently abandoned building and explore it. Peri discovers a sign saying "" — a sign, which means that they are on Earth. Peri begins to mourn for her planet.
The Doctor asks what the relevance of this is, then asks why
Peri is not with him on the station. The Valeyard answers that she is
where the Doctor left her, and states that the Doctor's evident
temporary amnesia - a side-effect of being taken out of time - should
soon pass.
The Doctor goes into the complex alone because Peri is upset, but
she is captured by two masked figures. Meanwhile, Glitz and Dibber are
brought before Katryca, Queen of the tribe. Glitz claims that the totem
attracted the fireball that devastated Ravolox, and asks for it to be
taken down. The Queen tells him that others have asked for the totem to
be dismantled, and none have succeeded. Glitz and Dibber draw out their
guns, but they are overpowered and locked up.
The Doctor finds an underground complex, but is caught. He is
accused of spying, and sentenced to be stoned. The Doctor tries to
block the rocks with his umbrella, but is knocked unconscious.
The Valeyard proposes that the inquiry into the Doctor's
activities should become a full blown trial, with the penalty being the
termination of his life.
Other officials arrive and break up the stoning. The Doctor is still
breathing, but before he can be killed, Merdeen receives a message from
the Immortal stating that he wishes to question the Doctor. The
Immortal, revealed to be a huge humanoid robot, commands its two
assistants to release the service robot.
Peri is brought before Katryca, who informs Peri that as there are
few women, she will need to take many husbands. She is then put in the
same prison as Glitz and Dibber. They tell Peri their plan to destroy
the Robot. They are taken back to Katryca, who tells them that Glitz
will be sacrificed because of his attempt to destroy the great totem.
The Doctor is taken to the Immortal, who introduces itself as
Drathro. He commands that the Doctor work with the two assistants. The
Doctor identifies the problem, and tries to leave in order to fix it,
but Drathro does not allow him to leave, as his instructions were to
maintain an underground system. The Doctor electrifies the robot and
his assistants, and escapes. Drathro sends the service robot to track
down the Doctor. Meanwhile, Peri, Glitz and Dibber overpower the guards
and escape. Dibber remains behind to plant a bomb on the Black Light
converter, whilst they go to the underground complex.
In Marb Station, Merdeen tells Balazar that there has been no fire
for hundreds of years, and that he should leave the complex. They
encounter the Doctor, and Merdeen implores him to help Balazar escape.
Peri, Glitz and Dibber, pursued by tribesmen, find the Doctor, and they
flee into the Marb Station, but are trapped between the tribe and the
service robot. The tribesmen shoot at the service robot and disable it.
The Doctor tries to re-enter the underground complex, but the tribesmen
insist they all return to the village. There, The Doctor is brought
before Katryca, but she is unimpressed with his explanation of the true
nature of the Totem, and puts them all back in the prison cell. Glitz
confirms that the planet is actually Earth.
Drathro reactivates the service robot, and send it to the village.
It breaks into the building with the Doctor, stuns him and takes him
away. The tribesmen disable the service robot, and decide to attack the
Immortal's castle to steal his technology. Peri rescues the Doctor from
the service robot, and they set off to the underground complex to stop
Katryca and disable the black light system. Katryca and tribesmen
arrive at the Castle, where they are confronted by Drathro,. He
electrocutes Katryca, and dismisses the rest of the tribe.
The Doctor enters Drathro's domain, promising to help repair the
black light system. However, he determines it to be beyond repair, and
tells Drathro that he must shut down the Black Light System to prevent
a massive explosion. Drathro refuses to allow that as it would mean its
own destruction. The Doctor pleads with him, saying that the explosion
could destroy the entire universe, but that only makes Drathro
determined to allow what he thinks is a unique event.
Balazar and Peri plead with Merdeen to help them, noting that he
would die if the converter exploded. Glitz and Dibber arrive and follow
them into the Castle through a food chute. Drathro attempts to kill by
turning on the food processing system, but Dibber shoots him through
the wall. Glitz tells Drathro that they have black light on their ship,
and offers to take the robot to the Andromeda Galaxy. Drathro agrees,
and leaves with Glitz and Dibber.
The Doctor realises that the black light system has already begun to
self-destruct, and that all he can do is prevent it starting a chain
reaction. The system explodes, but the blast only destroys the Castle,
and as a result Drathro collapses. The Doctor and Peri leave Merdeen
and Balazar to take the remaining inhabitants to a new life on the
surface.
The Doctor announces to the court that he has saved the
Universe, and starts to present his defence. The Valeyard warns the
Doctor that he has more evidence to come, and that the Court will
demand the Doctor's life at the end.
Continuity
The reason why Earth has become Ravalox, as well as the reasons for the Fireball, are explained in , the final part of the Season.The relationship between the Sixth Doctor and Peri is less abrasive
in this story than in the previous season. Both Colin Baker and Nicola
Bryant wanted to show how travelling together had made their characters
less combative and argumentative. Both this and the changes in their
appearances, particularly Peri's hairstyle and mode of dress suggest a
long gap between this story and their previous on-screen appearance in and allowing for "unseen" adventures in the spin-off media to be placed there.Early in Part One, the Doctor appears to be about to reveal his
surname for the first and only time in the entire series (but see , and further discussion in ).The Inquisitor and the Valeyard reference the events of .The Doctor's claim that he cannot be on trial as

Time Lord policy of non-interference, as opposed to specifically
forbidding a Time Lord meeting a past or future incarnation and
therefore interfering with his own history, as stated in earlier

Preproduction
In February 1985, the BBC announced that the planned twenty-third season of Doctor Who had been canceled. After vocal protests by the press and Doctor Who fans (including a charity single, ),
the BBC announced that the progamme was merely on "hiatus", and would
return in September 1986. Several stories which had been planned or
commissioned for the original Season 23 were in favour of an overarching "trial" theme, reflecting the fact that the programme itself was on trial at the BBC.
This story was the last complete Doctor Who story written by . Its plot is similar to Holmes' first contribution to Doctor Who, . In both stories, an alien machine subjugates a humanoid civilization and forces its brightest young people into its service.

Production
The opening model shot of the Time Lord Space Station where the

From this serial onwards, all location work would be recorded on
Outside Broadcast (OB) tape instead of 16mm film. This practice would
continue until the end of the series. The only footage shot on film for
this episode was the opening special effects shot of the TARDIS. The

since the early 1980s on the grounds that they were cheaper, and mixed
with studio-shot material better. John Nathan-Turner had actually
wanted to switch to OB shooting as early as 's first season in 1982, but met with resistance from the directors working on the show at the time.
