5V. Doctor Who - Logopolis

Season Eighteen

Script Editor: Christopher H. Bidmead; Writer: Christopher H. Bidmead; Produced by: John Nathan-Turner; Director: Peter Grimwade; Designer: Malcolm Thornton; Incidental Music: Paddy Kingsland;

The Doctor has an idea that may repair the chameleon circuit. For this the Doctor needs the exact measurements of a police box, and there is one on the Barnett Bypass in 1981. But before the Doctor can materialise around it, someone else already has done.

In the same lay-by two women have car trouble. While Tegan enters the police box, thinking it is real, someone else has emerged, and Tegan's aunt has been shrunk. In order to get rid of whatever has entered the TARDIS, the Doctor plans to materialise underwater and open the doors. The TARDIS misses, and materialises aboard a ship, where Doctor meets the Watcher.

With the measurements for a police box the Doctor materialises the TARDIS on Logopolis. The Logopolitans have the necessary skills to recalculate the block transfer computation, but the calculations are interfered with, and when applied the TARDIS shrinks.

The Watcher has also sent for Nyssa, and the Doctor, Adric, Tegan and Nyssa find that the culprit is the Master, who plans to hold the Universe to ransom. The plan backfires and entropy destroys the Traken Union, and Logopolis.

Logopolitans had copied the Pharos project on Earth. To fix the problem the Doctor, his companions, and the Master, travel to Earth. The Doctor manages to halt the entropy, but in a battle with the Master the Doctor falls from a radar dish and triggers his regeneration...
