The narrative also tracks the Doctor and Benny as they attempt to survive and understand their situation within this unfamiliar historical setting, dealing with strange phenomena and local politics while trying to find a way back to their own time. The story culminates in a confrontation where their differing perspectives on the world and the nature of their involvement lead to a violent climax and a bittersweet separation.
