Underworld

Written by Bob Baker and Dave Martin

"Perhaps those myths are not just old stories of the past, you see, but prophecies of the future. Who knows?"

The TARDIS lands in a Minyan spaceship. The crew is on a quest to find the Minyan race banks, which are stored in a missing ship known as the P7E. The quest leads to an underground labyrinth of caves at the centre of a newly-formed planet. But the P7E's computer has ideas of its own, and doesn't look kindly upon its new visitors.
