Classic Doctor Who Season 15 Episode 17 Underworld: Part 1

The Doctor and his companions, Leela and K-9, arrive on a spaceship in the midst of a crisis. The ship is on a mission to recover a long lost race's ancient texts, but they have become stuck in a black hole. Desperate for a way out, the ship's captain, Jackson, makes a risky maneuver that sends them crashing onto a planet. The planet is believed to be the only one capable of supporting life other than Earth and has been nicknamed "the underworld" by its inhabitants due to its underground cities and tunnels.

As the crew begins to explore their new surroundings, they are confronted by the inhabitants of the planet - a race of beings who appear to be made entirely of metal. These beings, known as the Minyans, are on a quest to recover their long lost race's ancient texts, which they believe will give them the knowledge and power they need to rebuild their civilization. The Doctor and his companions quickly discover that the Minyans are not the only ones searching for these texts. A group of space pirates, led by a man named Herrick, is also on the planet and has set its sights on the Minyans' prize.

The Doctor and Leela soon find themselves caught up in the middle of a dangerous power struggle between the Minyans and the space pirates. As they try to navigate the treacherous underground tunnels and caverns, they begin to realize that there is more to this planet than meets the eye. They discover that thousands of years ago, a race known as the Time Lords had visited this planet and had somehow managed to transform the planet's inhabitants into the metal creatures they now are.

As they try to unravel the mystery of the ancient texts and the planet's true history, the Doctor and his companions face numerous challenges and obstacles. They are pursued by Herrick and his henchmen, who will stop at nothing to get their hands on the texts. They encounter dangerous creatures that lurk in the planet's depths, and they must also contend with the Minyans themselves, who are becoming increasingly desperate and unstable in their quest for power.

Throughout it all, the Doctor remains determined to uncover the truth about this strange and mysterious planet. He uses his wit, intelligence, and knowledge of science and history to try and piece together the puzzle that surrounds the ancient texts and the planet's past. Along the way, he and his companions learn valuable lessons about bravery, loyalty, and the importance of standing up for what is right.
