In Doctor Who: The Macra Terror, the Second Doctor, Polly, Ben, and Jamie arrive on a human colony called New Earth. The colonists are under the impression that they are living in a perfect society, where they can enjoy endless leisure activities and live in peaceful harmony. However, the Doctor and his companions soon discover that the colony is being controlled by a race of giant crab-like creatures known as the Macra.
The Macra have enslaved the human population, using mind control to keep them happy and obedient. The Doctor and his companions try to uncover the truth behind the Macra's control over the colony, but they must do so while avoiding detection and battling the Macra's minions.
As the story unfolds, the Doctor and his companions encounter a number of characters who are struggling to break free from the Macra's grasp. They include a rebellious young woman named Medok, who has been labeled a delinquent for speaking out against the colony's leaders, and a scientist named Control who has been experimenting with mind control himself.
With the help of Medok and Control, the Doctor and his companions devise a plan to overthrow the Macra and free the colonists. They engage in a final battle against the creatures and ultimately succeed in destroying them and restoring the colony to a more natural state.
Overall, Doctor Who: The Macra Terror is a tense and engaging sci-fi adventure, with strong performances from the cast and some memorable creature design. It stands as a classic example of Doctor Who's ability to tell compelling stories while exploring deeper themes about power, control, and rebellion.
