The episode was written by Christopher H. Bidmead and directed by Fiona Cumming. The episode stars Peter Davison as the Fifth Doctor, Janet Fielding as Tegan Jovanka, and Mark Strickson as Vislor Turlough.

The episode begins with the Doctor regenerating, which means that he is changing into a new body. This regeneration process results in the Doctor losing his memory, and the new version of him must learn who he is and regain his abilities. The TARDIS, the Doctor's spaceship, is also severely damaged during the regeneration process, leaving the Doctor and his companions stranded in space.

The Doctor's companions, Tegan and Turlough, attempt to help the Doctor recover, but they soon find themselves in trouble when they discover that the TARDIS is trapped in a state of temporal grace. This means that they cannot leave or be harmed while inside the TARDIS, but it also means that they cannot receive help from outside the TARDIS.

The Doctor decides to take his companions to the planet Castrovalva, hoping that it will provide a safe haven while he tries to regain his memory and repair the TARDIS. However, when they arrive on Castrovalva, they discover that the beautiful city is not what it seems. It is an intricate, three-dimensional trap designed to ensnare them and keep them there forever.

The trap is the creation of a mysterious and powerful entity known as the Master, a renegade Time Lord who has a long history of trying to kill the Doctor. The Master has used his advanced technology to create a complex hologram of the city of Castrovalva, which is used to trick the Doctor and his companions into thinking that they are safe and secure.

As the Doctor struggles to regain his memory and escape the city, he also discovers that the Master is planning to destroy Castrovalva and kill everyone inside. The Doctor must use his wits and knowledge to foil the Master's plans and save his companions and the people of Castrovalva.

Overall, Doctor Who: Castrovalva is an exciting and suspenseful episode that showcases the wit and intelligence of the Doctor.
