Watch Doctor Who: Underworld

Doctor Who: Underworld is a classic science fiction television show produced by the British Broadcasting Corporation (BBC) in 1978. Underworld is an adventure in time and space featuring the enigmatic Time Lord known only as the Doctor, who travels in the TARDIS, a time machine that takes the shape of an old-fashioned British police box. In this particular episode, the Doctor and his traveling companion Leela find themselves in the middle of a galactic war in which the last remaining members of a once-great race are fighting to survive.

The story begins with the Doctor detecting a distress signal coming from an unknown source, prompting him to investigate further. He and Leela leave the TARDIS and soon find themselves on a massive spaceship that is being chased by a fleet of smaller ships. Upon boarding the ship, they learn that it belongs to the Minyans, the last surviving descendants of the race that created the universe. They are on a quest to find a fabled planet called P7E, which they believe contains vast reserves of valuable minerals and the key to their survival.

The only problem is that the planet is lost, and the Minyans have been searching for it for countless generations without success. The Doctor offers to help them locate the planet, and soon sets off on a dangerous journey deep into the belly of the "Underworld" - a vast network of tunnels and caves that stretch across the universe.

Along the way, the Doctor and Leela encounter all sorts of dangers, from treacherous natural hazards to deadly robotic guardians that protect the sacred secrets of the universe. They also meet a group of exiled slaves who have been living in the tunnels for generations, and who are desperate to escape and find a new home. As the Doctor and his companions delve deeper into the Underworld, they discover shocking secrets about the Minyans' past and the true nature of their quest for P7E.

As always, the Doctor uses his wit and ingenuity to outsmart his enemies and find a way to save the day. Along the way, we get to see all sorts of classic sci-fi tropes, from spaceship battles to ancient civilizations to spooky underground dwellings. The show also has a strong sense of humor, with plenty of witty one-liners and lighthearted moments interspersed with the action and drama.
