Doctor Who: The Wheel of Ice

Hurtling through a vortex beyond time and space is a police box that's not a police box.

The colony has been plagued by problems. Maybe it's only a run of bad luck, but the equipment failures and thefts of resources have been increasing. And there are stories among the children of mysterious creatures glimpsed aboard the Wheel. Some of the younger workers are even refusing to go down into the warren-like mines any more.
