The Doctor is back with a brand-new adventure in the third episode of season 19 of Doctor Who, titled "Castrovalva." This episode picks up where the previous one left off, with the newly-regenerated Doctor struggling to regain his strength and memories.

The TARDIS brings the Doctor and his companions Nyssa, Tegan, and Adric to a seemingly idyllic city on the planet Castrovalva. Here, they encounter a group of friendly locals who welcome them with open arms and offer them a helping hand. However, things are not as they seem in Castrovalva, and the Doctor soon realizes that they have stumbled upon a trap set by his arch-nemesis, the Master.

As the Doctor and his companions try to unravel the mystery of Castrovalva, they encounter a series of mind-bending challenges and obstacles that test their wits and ingenuity. They must navigate a twisted maze of illusions and deception as they uncover the Master's plan and try to stop him from achieving his evil goals.

One of the standout features of this episode is the stunning visuals and effects used to bring the strange, surreal landscape of Castrovalva to life. The city is a labyrinthine maze of Escher-like staircases and impossible architecture, and the Doctor and his companions must use all their skills to make their way through it.

Another highlight of "Castrovalva" is the introduction of the character of Nyssa, a young woman from the planet Traken who becomes one of the Doctor's most loyal and trusted companions. Nyssa is a brilliant scientist and engineer who is able to help the Doctor to solve some of the complex puzzles that they encounter on Castrovalva.

Overall, "Castrovalva" is a thrilling adventure that will keep viewers on the edge of their seats with its twisty plot, mind-bending visuals, and unforgettable characters. Whether you're a die-hard Doctor Who fan or just looking for a fun sci-fi adventure, this episode is not to be missed!
