Doctor Who: Underworld (TV)

The TARDIS arrives on a Minyan space craft, the R1C, commanded by a man named Jackson. Jackson and his crew are on a long quest to recover the Minyan race banks from a ship called the P7E which left their planet centuries ago. The Doctor helps to free the R1C after it becomes buried in a meteorite storm, but it then crashes into another newly-formed planet. Inside the planet is a system of caves at the heart of which is the P7E. The P7E's computer, the Oracle, was programmed to protect the race banks but subsequently went insane and - with the aid of its robotic servants, the Seers - imposed its rule upon the Minyan survivors and their descendants.
