`You can't rewrite history, not one line.' When the TARDIS materializes in an ancient Aztec temple, Barbara is mistaken for the reincarnation of the Aztecs' High Priest, Yetaxa. The time travelers soon find themselves caught up in a vicious power struggle that could cost them their lives, especially if Barbara continues to wield her influence in an effort to divert the course of history.
