Doctor Who: Galaxy 4 is a science fiction serial in which the Doctor and his companions land on a barren planet facing imminent destruction. Two alien species—the militaristic Drahvins and the peaceful Rills—are stranded there, each desperate for escape. The Doctor must navigate a moral minefield when the Drahvin commander Maaga demands his help evacuating only her own people, forcing him to confront questions of survival, sacrifice, and whose lives matter most. Tension mounts as the planet's countdown to annihilation accelerates and the true nature of each species is revealed.
