The Doctor, Bill and Nardole arrive on Mars, and find themselves in an impossible conflict between Ice Warriors… and Victorian soldiers. As the Martian hive awakens around them, the Doctor faces a unique dilemma - this time the humans, not the Ice Warriors are the invaders. When Earth is invading Mars, whose side is he on?
