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. So, 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 that 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
A mysterious blast renders the TARDIS crew unconscious. They awake disorientated and soon find that the TARDIS is malfunctioning strangely. As all the systems break down, the behaviour of the crew becomes more erratic. Soon the Doctor comes to believe that the school teachers have caused the problems to blackmail him into taking them home.

Gradually it becomes clear that the problems are a warning from the TARDIS. It seems that a spring has broken on the Fast Return Switch, causing the TARDIS to travel back through time towards the creation of the Solar System. The Doctor corrects the problem and the travellers are able to escape.

The Edge of Destruction (1)
The Doctor, while attempting to correct the TARDIS's faulty navigation circuits, causes a small explosion. The Doctor, Barbara, Ian and Susan are all temporarily 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, and 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, all 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, but that 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 in order 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 that 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.

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 in her teachers' innocence. The Doctor is threatening 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 that 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.
