Doctor Who: Logopolis

The Fourth Doctor, accompanied by his companion Tegan, travels to the advanced world of Logopolis, a planet that generates the universe's fundamental constants. However, Logopolis is decaying due to the interference of the Master, who is attempting to harness its power for his own nefarious purposes. The Doctor must race against time to restore balance and prevent the universe from collapsing, facing moral dilemmas and the imminent end of his current regeneration.
