Ep 7. Invasion of the Dinosaurs: Part 3

The Classic Doctor Who Season 11 Episode 7, titled "Invasion of the Dinosaurs: Part 3," follows the Doctor and his companion Sarah Jane Smith as they continue their investigation into the mysterious appearance of various dinosaurs in modern-day London. In the previous episode, they discovered that a group of scientists, led by a man named Professor Whitaker, had been transporting dinosaurs from different time periods and bringing them to present-day Earth using time travel technology. The purpose of this dangerous experiment is to reset humanity to an earlier time in history where the Earth was in a more pristine state.

As the episode begins, the Doctor and Sarah Jane are still trapped in Whitaker's time tunnel. Luckily, they are saved by UNIT (Unified Intelligence Taskforce), a military organization that has been tracking the unusual dinosaur appearances and is now working to stop Whitaker's dangerous plan. The Doctor and Sarah Jane team up with UNIT and set out to find Whitaker and his accomplices.

Meanwhile, in present-day London, chaos ensues as the public begins to realize the gravity of the situation. Dinosaurs are wreaking havoc on the city, causing destruction and terrorizing the population. The government declares a state of emergency and citizens are advised to stay indoors.

As the Doctor and UNIT close in on Whitaker's location, they discover that he has not acted alone. A group of eco-activists, known as the "Ecology Wardens," have been working with him to carry out the plan to reset the Earth's history. The Doctor and Sarah Jane are shocked to learn that the Ecology Wardens include some of their own friends, who seem to have been led astray by Whitaker's idealistic but dangerous plan.

The Doctor and UNIT are able to stop the time tunnel and shut down the technology powering it. But Whitaker and the Ecology Wardens are determined to see their plan through to the end, and they launch a full-scale attack on UNIT headquarters. The Doctor and Sarah Jane must face off against their own friends in a desperate struggle to prevent them from destroying the entire city.

As the fight rages on, the true motivations of the Ecology Wardens are revealed, and it becomes clear that they have been carefully manipulated by Whitaker for his own personal gain.
