Source-derived summary

The Ambassadors of Death is the third serial of the seventh season of the British science fiction television series Doctor Who, which was first broadcast in seven weekly parts on BBC1 from 21 March to 2 May 1970. The serial's script was credited to David Whitaker but completed primarily by Malcolm Hulke and Trevor Ray. It was directed by Michael Ferguson.

The serial is set in London, Hertfordshire and the Earth's orbit. In the serial, the alien time traveller the Third Doctor (Jon Pertwee) and the international organisation UNIT investigate the disappearance of astronauts who have lost contact with Earth. They become involved in a conspiracy and meet alien ambassadors who have arrived on Earth.

Plot

The United Nations Intelligence Taskforce, alongside Ralph Cornish (Ronald Allen)— Professor and Controller—attempt to make contact with the missing Mars Probe Seven and its two astronauts, who lost contact with Earth eight months earlier. When the recovery crew returns to earth, it is captured by General Charles Carrington (John Abineri), also abducting the missing astronauts. Carrington is now introduced to the Doctor by Sir James Quinlan (Dallas Cavell), the Minister for Technology, as head of the newly formed Space Security Department. Carrington says his actions were to protect the astronauts, as they have been infected with contagious radiation.

Editorial analysis

Why this record matters

The phrase “doctor Who serial” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q555683. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1970.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
