Another adventure for everyone's favourite Time Lord. The Doctor (Tom Baker) and Leela find themselves under suspicion of murder when the TARDIS lands on a Sandminer, a craft designed to mine valuable ores on alien planets. The vessel is manned by a huge staff of robots and a handful of humans, who are being killed off one by one. After preventing an attempted sabotage of the miner, the Doctor realizes that someone has managed to override the robots' programming, turning them into relentless killer machines.
