Doctor Who: Planet of the Dead (TV)

Tracking a mysterious energy signal, the Doctor boards a London bus upon which cat burglar Lady Christina de Souza is also a passenger. Suddenly, the bus is catapulted through a wormhole to San Helios, on the other side of the universe. The planet seems to be just one enormous desert, but after encountering stranded Tritovore traders, the Doctor and Christina learn that San Helios is meant to be a bustling world of billions. Soon, it becomes clear that the wormhole and the devastation of San Helios are linked... and the Earth may be destined for a similar fate.
