Through Leela, it gradually becomes apparent that the constant war between the Sevateem and the Tesh has been instigated by the god they both worship, Xoanon.

Xoanon, an all-powerful computer, is possessed by a desperate madness - a madness that is directly related to Doctor Who, that causes Xoanon to assume the voice and form of the Doctor, a madness that is partly caused by the Doctor and that only the Doctor himself can rectify!

In theory the TARDIS should be able to change its appearance to blend in unobtrusively wherever it happens to materialise. In practice, however, it always looks like a police box - a minor inconvenience the Doctor now hopes to correct.

Fixing the mechanism involves a visit to Earth and a trip to the planet Logopolis - normally a quite little place that keeps itself to itself.

And even the Master is horrified by the threat of total chaos he unintentionally precipitates - until he finds a way to turn the imminent destruction of the universe to his own advantage...
