Full revelation of Adrasta's wicked acts in maintaining her planetary monopoly on metal brings her reign to an end, but the victimized alien creature holds a secret: massive interstellar retribution for her crimes is headed their way, with doom for all, including those whose current short-sighted actions undermine the Doctor's efforts to save the planet in order to become new leaders of the old metal monopoly.
