This episode starts the 6th adventure for the Doctor (Hartnell) and his three companions. Encompansing episodes 27 through 30, this tale has the TARDIS landing inside an Aztec high priest's tomb. When they exit the tomb the doorway shuts leaving them unable to get back to it. When Barbara gets mistaken as the reincarnation of a the deceased, she gets it in her head that changing history a little might be a good thing, regardless of the Doctor's orders that history has to go unchanged. Her actions places them all in danger, as some of the Aztecs plot against them. This was a pretty good early Dr. Who story, William Hartnell acted superbly, as did the rest of the cast. The villains of the episode arc were a bit one-dimensional, but it didn't detract from my enjoyment of the show. I didn't always emphasize with the passive nature of the first Doctor, buts that's how he was.
