Runners of Korros

The Tenth Doctor, Romana, and K-9 land on the planet Korros, a desolate ice world run by a corrupt weapons company. The only people on the surface of the planet are the runners, weapon couriers who deliver weapons from slum to slum. To keep the runners occupied, the company scoops people out of there own time and let the runners hunt them down. A Tenth Doctor sequel to New Faces.
