The Edge of Destruction (TV story)

The Edge of Destruction was the third story of Season 1 of Doctor Who. The story is unique in the original series in that it is set entirely inside the TARDIS and features only the regular cast members.

The BBC initially committed to four episodes of Doctor Who. Mid-way through the production of An Unearthly Child, this was upped to thirteen. Together, An Unearthly Child and The Daleks only totaled eleven. With a tiny budget, The Edge of Destruction was commissioned to fill the remaining two episodes and fill out the season.

Narratively, the story was crucial as the events bonded the travellers so that they were no longer just mismatched people forced together, but a group who could trust one another. It also saw the first hint that the Doctor's TARDIS was not his own, shown by his lack of understanding of its abilities. The Edge of Destruction was the first instance of the Doctor namedropping historical figures.

Synopsis
As they slowly recover from the shock of being thrown to the TARDIS floor, the Doctor, Susan, Ian and Barbara all seem to be acting strangely. A number of unexplained events occur and suspicions are raised that some alien force may have entered the ship. The Doctor at one point even accuses Ian and Barbara of sabotage.

It gradually dawns on the travellers that what they have been experiencing is an attempt by the TARDIS itself to warn them of something. The Doctor ultimately realises that the Fast Return Switch he used when leaving Skaro has stuck, and the ship has been plunging back to the beginning of time and its own destruction.

Once the problem - a faulty spring - is corrected, the TARDIS returns to normal and the Doctor is forced to make some apologies.

The Edge of Destruction (1)
The First Doctor, while attempting to correct the TARDIS's faulty navigation circuits, causes a small explosion. The Doctor, Barbara, Ian and Susan are all rendered unconscious. Barbara is the first to recover and awakens Ian and Susan, who appear to have slight cases of amnesia. The Doctor is lying on the floor with a gash on his head. Susan recovers her senses enough to retrieve a special healing bandage from the ship's first aid kit and water from the food machine for her injured grandfather. Suddenly, Susan becomes convinced that an alien presence is on board and has seized control of the ship.

The TARDIS doors begin intermittently opening and closing whenever Ian moves towards them. When Susan attempts to operate the door switch on the console, she receives an electrical shock. As the Doctor revives, Barbara tends to him while Ian carries Susan to her room. There she stabs at him with a pair of scissors, rips her bed to shreds, then collapses.

Later, the Doctor, Barbara, and Ian discuss the situation, each alternating between clarity of mind and paranoid sniping. The Doctor checks the system controls with Ian's assistance, while Barbara checks on Susan, who has retrieved the scissors and attempts to attack her with them, but stops herself from doing any real harm.

When the Doctor attempts to determine their location with the view scanner, he finds only images which he recognises as records of the TARDIS's previous journeys. The last image, a picture of planets, a solar system and an explosion, puzzles him. Susan by now is convinced that not only has an alien intelligence entered the ship, it has taken over one or more persons on board. When the Doctor opens the TARDIS doors, they quickly close themselves as Ian moves towards them. Soon, the Doctor and Susan begin to accuse their human companions of sabotage to get the TARDIS back to England in 1963. Barbara angrily refutes the Doctor's suspicions with a recap of their recent adventure on Skaro, where she and Ian risked their lives to save the Doctor and Susan from the Daleks and cites Ian's bravery in the Cave of Skulls. Her tirade is abruptly ended when she sees the cathedral clock the Doctor keeps in the console room has melted, a sight which horrifies her. They all check their watches and see the same has happened to their timepieces.

The Doctor excuses himself from the room and returns with a tray full of drinks, a "nightcap" which he offers as a peace offering to his companions. Barbara, Susan, and Ian retire to their quarters and drink the nightcaps.

After looking in on his companions to confirm they are asleep, the Doctor returns to the console. As he examines it, a pair of hands swing him around and grab him by the throat.

The Brink of Disaster (2)
The Doctor's attacker is none other than Ian. A strange force has overridden the effects of the drug and compelled Ian to stop the Doctor from operating the TARDIS controls. Ian recognises the Doctor and collapses. Barbara enters and finds herself and Ian openly accused by the Doctor of sabotage.

As Barbara tries to reason with the Doctor, Susan enters the room and sides with her grandfather, but then finds herself believing her teachers' innocence. The Doctor threatens to put the humans off his ship when an alarm sounds. The fault locator lights up, showing faults in every system. An explosion rocks the ship. The Doctor realises the TARDIS's power source, located beneath the console, is trying to force its way out and they are only minutes from destruction.

Faced with a common peril, the travellers forget their differences and begin to work together. Barbara deduces that the strange events are an attempt by the TARDIS itself to warn the crew that something is wrong. The Doctor traces the problem to a broken spring in the Fast Return Switch. The malfunction is causing the TARDIS to head back to the creation of a Solar System; the strange events were just the TARDIS's attempts to warn its passengers before the ship is destroyed. Fixing the switch brings all back to normal. The Doctor apologises to Ian, who accepts his apology straight away. Barbara needs more convincing but she is eventually won around by the Doctor and the foursome prepare to go out and explore their new surroundings, this time a snowy planet. When Barbara and Susan go outside they discover a giant footprint in the snow.

Story notes

 * This is the first story - and only full-length story - featuring only the Doctor and his companions.
 * The first episode, "The Edge of Destruction", takes place entirely in the TARDIS. The Children in Need Special, Time Crash, Space/Time, and technically Amy's Choice are other televised stories set entirely in the TARDIS. The Meanwhile in the TARDIS mini-episodes of the Complete Fifth Series Box Set and the Night and the Doctor mini-episodes from the Complete Sixth Series Box Set were also set entirely in the TARDIS (with the exception of the Night and the Doctor episodes First Night and Up All Night)
 * This story is also known as Inside the Spaceship and The Brink of Disaster, as well as being often wrongly referred to as Beyond the Sun.
 * All episodes exist in 16mm telerecordings.
 * Both episodes were recovered from the negative film prints discovered at BBC Enterprises in 1978.
 * An Arabic print is also held.
 * This story was written to make up the number of episodes and meet the show's commitment to the BBC. The show was initially commissioned for 13 episodes. An Unearthly Child had four and The Daleks had seven, so an additional two episodes were required in case the show should be cancelled at this point.
 * Some of the music from this story was released as Doctor Who at the BBC Radiophonic Workshop, Volume One - The Early Years, 1963 - 1969.
 * This was one of the stories selected to be shown as part of BSB's Doctor Who Weekend in September 1990. The episodes were shown in the wrong order, but were repeated in the correct sequence later that weekend.

Production errors

 * There is a shadow visible on wall when Barbara tries to wake Ian up.

 * While the Doctor is describing the birth of a new solar system, a cough can be clearly heard.
 * Susan is wearing ankle-socks in the reprise, but afterwards she is not.

Continuity

 * The TARDIS and its crew were placed into similar peril by the Master in DW: Castrovalva.
 * A similar display of the TARDIS's semi-sentience is displayed in PDA: The Roundheads.
 * The TARDIS's abilities are further expanded upon in DW: Boom Town and DW: The Parting of the Ways.
 * The Fast Return Switch is again used in PDA: The Witch Hunters, BFA: Seasons of Fear and Neverland.
 * The TARDIS power source is beneath the central console. DW: Boom Town suggests this is in fact the Heart of the TARDIS.
 * The TARDIS is later similarly threatened by the The Silence in The Pandorica Opens/The Big Bang.
 * As revealed in The Pandorica Opens, the TARDIS's destruction would, under certain circumstances, obliterate the Universe.
