Ep 15. The Ambassadors of Death (4)
- April 11, 1970
The Doctor (played by Jon Pertwee) and UNIT are called in to help when the Mars Probe 7 spacecraft goes missing. It turns out that the astronauts on board have been kidnapped by a group of aliens called the Ambassadors of Death, who are using them for their own unknown purposes. The Doctor and UNIT must rescue the astronauts, stop the Ambassadors from carrying out their plans, and figure out why they are on Earth.
As the Doctor and UNIT investigate, they uncover a web of government conspiracies and lies. The British government has been using the Mars Probe 7 missions as a cover for secret experiments involving a new technology that allows people to travel instantaneously anywhere on Earth. The experiments have caused the Ambassadors of Death to become active and start kidnapping people in order to learn more about the technology. The Doctor and UNIT must work to stop both the Ambassadors and the British government from causing any more harm.
Meanwhile, the kidnapped astronauts have been brainwashed by the Ambassadors into carrying out their bidding. They are sent out to steal the technology needed for the Ambassadors' ultimate plan: to start a war between Earth and their own planet. The Doctor and UNIT race against time to save the astronauts and uncover the Ambassadors' true intentions.
Throughout the episode, the Doctor also deals with the consequences of his actions in the previous episode, where he broke the Time Lords' laws and stranded himself on Earth. He struggles with his desire to leave and explore the universe, but ultimately decides to stay and help UNIT fight the aliens.
As the episode reaches its climax, the Doctor and UNIT must defend themselves against the Ambassadors' attempts to take the stolen technology. With the help of the kidnapped astronauts, they manage to foil the Ambassadors' plans and save the day.
In the end, the Doctor reflects on the events of the episode and his decision to stay on Earth. He acknowledges the responsibility he feels towards protecting humanity and vows to continue fighting for the greater good. The episode ends with the Doctor and UNIT beginning their next adventure, ready to face whatever threat comes their way.
