The Doctor's latest regeneration has proven more unstable than his previous ones. His two assistants, Tegan and Nyssa, help him recuperate on the tranquil planet of Castrovalva.

Adric has been captured by the Master, who is taking advantage of the Doctor's weakened state to ensnare him in an elaborate trap whose recursive nature threatens to destroy his mind.

As the Doctor begins to recover he realises that the Master's trap for Adric is even more intricate than he could have imagined and that he will stop at nothing to gain his revenge over the Doctor.

The Visitor

Things to look out for:
Peter Davison's hair is light brown at the end of Logopolis, when he first appears as the newly regenerated Doctor, but has changed to near platinum blond as he is helped through the field to the TARDIS at the start of Castrovalva.

All 4 episodes exist.


Director Fiona Cumming cast different actors for the security guards chasing the companions at the start of episode one than Peter Grimwade had used at the end of Logopolis.

In the Zero Room sequence, the image is horizontally flipped. This has the effect of making The Doctor's collar question marks appear reversed. The error was gleefully pointed out by Peter Davison in the DVD commentary.

In Part 1, The Doctor leaves behind items of clothing including the fourth Doctor's scarf and a shoe, despite the fact he was wearing wellington boots when he regenerated.
