The Wheel. A ring of ice and metal turning around a moon of
Saturn, home to a mining colony supplying a resource-hungry
Earthâ€”a colony plagued by problems. Equipment failures and

And then one of them, surfing Saturnâ€™s rings, saves an
enigmatic blue box from destruction.
Once on the Wheel, the Doctor and his companions, Jamie and

some as the source of the ongoing sabotage. They soon find
themselves caught in a mystery that reaches back to the
creation of the solar system. A mystery that could destroy
the Wheelâ€”and kill them all...
