Doctor Who: Logopolis

LOGOPOLIS - Tegan gets a puncture in her car tire on her way to her first flight as an air stewardess. She seeks help from the Police Box on the verge nearby - but actually it's the TARDIS, inside of which the Doctor and Adric are investigating the Police Box that they have materialized around in order to take measurements of it for their trip to Logopolis, the city of Logic, which is inhabited entirely of mathematicians. The Doctor is venturing there because his friend Monitor, leader of the Logopolitans, has devised a way to create solid objects out of numbers and they can also help the Doctor repair his chameleon circuits in the TARDIS. While Tegan loses her way inside the TARDIS, the Police are inspecting her car, and the Doctor and Adric keep circling through a gravity bubble from one police box TARDIS to another until the Doctor ventures outside the original TARDIS. There he runs into the Police who suspect him of the crime and show him what they have found: the body of her Aunt Vanessa in the back seat - shrunk to the size of a doll - on of the Master's calling cards. With Adric's help as a diversion, the Doctor eludes the police and heads back to the TARDIS to continue his planned trip. However, a mysterious figure (actually the Watcher, the Doctor's new self-to-be) has been glimpsed all day long in the distance and eventually gives the Doctor some very important news about the future. When Adric later questions him about the encounter, the Doctor can only enigmatically warn the boy that some enormous trial lies ahead. At the moment of arrival at Logopolis, a frightened Tegan emerges from the TARDIS interior. The three of them are taken to the Main Logic Room at the Central Register, which Monitor admits to being modeled around the famous Pharos computer room at Cambridge, for Logopolis maths can make a copy of any object through time and space. Which is why the Master follows the Doctor and his companions to Logopolis - but he has a few tricks up his sleeve and since he has stolen Tremas's body, he uses Nyssa to try and defeat the Doctor and to become the ruler of the universe. But there is one problem, the Master hasn't taken into consideration that if the Logopolitans stop their computations, then the whole universe, which has been temporarily stabilized by Logopolitan created voids, will deteriorate. Against his better judgment, the Doctor joins forces with the Master to save the universe, but is double crossed when the Master announces his plan to make slaves out of the human race, or let them die if they refuse his offer. The Doctor saves the day by disconnecting the Master's necessary cable, but falls to his death where the Watcher then regenerated into the next carnation of Doctor Who.

The Doctor and Andric head to Earth to fix the TARDIS's chameleon circuit. Once there they face danger involving a newly regenerated Master and a feisty young air hostess named Tegan Jovanka. How can the people of the distant and mysterious planet Logopolis help? And just who is the strange, ghostly figure watching the Doctor's every move?
