Season 20, Episode 127 - "Terminus"
15 February, 1983
The sabotaged TARDIS has to make an emergency landing on a ship that docks with a derelict space station at the centre of the known universe. However, it turns out that the station is not as derelict as it appears. It is Terminus, the last stop and receiving point of the ship's cargo of lepers. And as the saying goes, nobody returns from Terminus.
