The Ambassadors of Death (TV story)

The Ambassadors of Death was the third story of Season 7, and was first broadcast in seven weekly parts from 21st March to 2nd May, 1970.

Synopsis

The Doctor joins UNIT's investigation into the mystery surrounding Mars Probe 7. Space Control, headed by Professor Ralph Cornish, has had no contact with the astronauts on board since it started back from Mars seven months ago, and now the Recovery 7 rescue mission has run into similar difficulties.

This second ship does get back to Earth, but the astronauts are kidnapped after landing and Liz Shaw notices that the Geiger counter is at maximum. It transpires that the ship's occupants were not the human astronauts after all but a trio of radiation-dependent alien ambassadors who had swapped places with them.

The Doctor makes a solo flight in Recovery 7 and docks with Mars Probe 7, still orbiting in space. He is then intercepted by a huge alien spaceship and taken on board, where he finds the real astronauts unharmed. The aliens' Captain threatens to destroy the Earth unless their three ambassadors are released.

The Doctor is allowed to go and, after returning to Space Control, discovers that the kidnapping of the ambassadors is part of a scheme devised by xenophobic ex-astronaut General Carrington to discredit the aliens and convince the world's authorities to wage war against them. The Doctor and UNIT are able to thwart his plans and arrange the safe exchange of ambassadors for astronauts.

Plot

With the United Nations Intelligence Taskforce providing security, the British Space Programme under Professor Ralph Cornish oversees the launch of the Recovery Seven probe. This has been sent to Mars to make contact with the missing Mars Probe Seven and its three astronauts, who lost contact with Earth eight months earlier. The pilot of Recovery Seven, Van Lyden, makes contact with the Probe but is then silenced by a piercing unearthly sound. The noise troubles the Doctor who travels with his assistant Liz Shaw to the Space Centre to investigate the situation, offering insights into the origin and meaning of the sound, which he interprets as coded messages. He also identifies a reply message sent from Earth and this is pinpointed to be coming from a warehouse seven miles away. Led by Brigadier Lethbridge-Stewart, UNIT troops attack the warehouse and engage in a gun battle with troops organised by General Carrington.

Meanwhile Recovery Seven has returned to Earth and while UNIT is transporting it more of Carrington’s troops stage an ambush and steal the vessel. The Doctor relocates it, by which time it is empty. Carrington has ensured the contents – three space suited astronauts – are detained elsewhere, feeding them radiation to keep them alive. Carrington is now introduced to the Doctor by Sir James Quinlan, the Minister for Technology, who explains that he is head of the newly formed Space Security Department, and that his actions were to protect the astronauts as they had been infected with contagious radiation. Quinlan states that they did not want the public to become panic-stricken and so Carrington had been acting with authority in his actions.

By the time Carrington takes the Doctor and his friends to meet the astronauts the situation has changed again. A criminal named Reegan has organised their abduction, killing the soldiers and scientists protecting them. When the Doctor and Liz examine the situation they work out that human tissue could not have withstood the degree of radiation emitted to the astronauts, who are still in orbit, meaning the three space suits contain alien beings instead. Reegan now engineers the kidnapping of Liz Shaw to aid his own scientist, Lennox, a disgraced Cambridge professor, in maintaining the alien beings while they are incarcerated. Together they build a device to communicate with and control the aliens, who are sent on a killer rampage at the Space Centre, killing Quinlan and others. Liz later helps Lennox escape, but his bid for freedom is cut short by Reegan’s merciless revenge.

Despite the obstruction of the authorities, Ralph Cornish is determined to organise another space flight to Mars to investigate the situation. With Quinlan dead, the Doctor now decides to pilot the Recovery Seven probe ship himself. As he prepares to blast off Reegan tries to sabotage the probe by increasing the feed of M3 variant, but the Doctor survives the attempt on his life and succeeds in piloting the probe so that it connects with an enormous spacecraft orbiting Mars. Aboard the spaceship the Doctor discovers the three original astronauts are unharmed but mentally deluded into believing they are in quarantine. An alien being now reveals itself to the Doctor and explains the humans are being held aboard the craft pending the safe return of the Alien Ambassadors. They had been sent to Earth following a Treaty between the race and mankind, but the terms of this agreement have now been broken because of the detention of the Ambassadors. The Doctor offers his personal guarantee to help return the Ambassadors to their mother ship and resolve the conflict before a state of war is declared, and is permitted to leave the alien craft and return to Earth.

When the Doctor touches down he is gassed and kidnapped by Reegan, who takes him to Liz. Reegan’s real paymaster and the real organiser of the situation is revealed to them: General Carrington. The General reveals his actions have been prompted by xenophobia driven by his own encounter with the alien beings when he piloted Mars Probe Six some years earlier. His co-pilot, Jim Daniels, was killed on contact with the aliens and the General signed the treaty with the aliens to lure three of their number to Earth, where he hoped he could unveil their real agenda of alien invasion. The use of the ambassadors to kill people was similarly done to arouse public opinion against them. The next phase of his plan is to force the Ambassadors to confess their plot on public television. Leaving the Doctor and Liz working on a new and improved communication device to translate the aliens, Carrington departs for the Space Centre, where he aims to unmask the alien Ambassador before the eyes of the world – and then call on the powers of the Earth to blast the spaceship from the skies.

UNIT soldiers raid the secret base and rescue the Doctor and Liz, apprehending Reegan and his thugs. The Doctor races to the Space Centre and he and the Brigadier apprehend Carrington before he can make his broadcast. Sadly, he is taken away, protesting he was only following his moral duty. The Doctor arranges for Cornish and Liz to send the Ambassadors back to their own people, after which the three human astronauts will be returned.

Story Notes

Working titles for this story included The Invaders from Mars, Invaders from Mars and The Carriers of Death.
An unusual title sequence was used for this serial, with the sequence cutting off after the show's logo, repeating the previous week's cliffhanger, then returning to the titles for the serial's name, writer and episode number.
This was the last story written for Doctor Who by David Whitaker. He considered it his least favourite story on which to work.
The plot of this story resembles that of The Quatermass Experiment, where an astronaut who has apparently returned to Earth has in fact been replaced by an alien life form.
Although the entire story was made on colour videotape, only the first episode is retained in this format; in fact, it is the earliest episode that survivesin the series' original videotaped format, either in colour or B&W. It is not, however, the first to exist in colour: Spearhead from Space, the first serial of that season, was (uniquely for the series) produced on 16mm colour film and survives in that format. The remaining six episodes survive only as black and white film recordings and poor-quality domestic colour recordings made from a US transmission in the 1970s. This recording is severely affected by a rainbow-coloured pattern of interference that at times overtakes the entire picture.
In 2002, a restoration project for the story's VHS release combined the usable colour information from the domestic recordings with the black and white picture from the film prints, creating a high-quality colour picture. In total, more than half of the serial's running time is presented in colour on the VHS release, including all of Episodes 1 and 5, and sections from 2, 3, 6 and 7. The remaining footage, including all of Episode 4, was not deemed suitable for colour restoration, and so remains in black and white. There are also fan efforts to colourise the serial.
Ian Levine stated that he was attempting to colourise the current B&W episodes of this serial. He also stated that there would be full colour copies of all the episodes in this serial in the BBC archives by the end of 2006. (Currently this is unconfirmed)
