The locator leads the Doctor and Romana to the third moon of Delta Magna. The moon is a swamp-covered world on which a small crew of humans maintains a refinery and are in constant feud with the simpler humanoid creatures known as swampies who also live there. Their God, a giant octopus-like creature called Kroll, makes an appearance and threatens the refinery.
