Frontios
"Frontios buries its own dead", or so the saying goes.
The Doctor, Turlough and Tegan are forced into landing on the remote planet of Frontios, a human colony where deaths go unaccounted for. Under constant threat from lethal meteorite bombardments, few of the doomed colony members realise that the ground of Frontios itself opens up and devours the unwary. Not permitted to assist, the Doctor's attempt to leave is thwarted when the unimaginable occurs: the TARDIS is destroyed.
All the while, burrowing undetected below the planet's crust, an alien force prepares a final and gruesome fate for all humanity...

The planet Frontios, in the distant future. Following Earth's destruction, a tiny colony struggles to eke out a life on this desolate world. But where do the bombardments that threaten them originate from? Little does the Doctor suspect that somewhere nearby lurks a power capable of ripping even the TARDIS apart…
Following the destruction of the TARDIS, the only part of it left is the hat stand. So Turlough uses it as a weapon! Plantagenet gets swallowed by the earth, and Norna and Turlough discover the Tractators.
Trying to rescue the Doctor from the Tractator's trap, Tegan lands them both in even more trouble. Turlough goes a bit mad, and reckons he knows the evil of the Tractators from old.
The Doctor tries to deal with the Tractator's cunning plan, despite Turlough's best intervention. They discover the splintered TARDIS in the tunnels beneath the planet's surface, but how will they put it together again?
