Sue and her brother, Eddie, on vacation in London, take a tour of Terror Tower, a scary prison and torture chamber from medieval times. The guide tells the group a horrifying tale of a young prince and princess sentenced to execution in the Tower in the 15th century. Then strange things begin to happen: Sue and Eddie are the only ones to notice the ghoulish wax figures moving as if they were real . . . and ghostly images call out warnings to them. Suddenly, Eddie and Sue find themselves separated from the group! Who is that spooky guide dressed in black? What kind of strange, old English money has suddenly replaced their own? And why can't Eddie and Sue remember their last name—or where their parents are? These questions haunt them as they travel back in time to the middle ages—trying to escape the fate meant for the young prince and princess in the evil Terror Tower.
Differences from the book
- The episode is mostly faithful to the original story, save for an alteration at the climax; the Lord High Executioner still possesses Morgred's three white stones at the end of the episode, and Eddie pickpockets them from him a second time (instead of Morgred), allowing Morgred to save all three of their lives. In the book, Morgred would have been spared for refusing to send the children again and apparently just never considered sending himself as well. Additionally, in the twist, it is shown that the Executioner managed to seize back one of Morgred's stones, allowing himself to return to the present.
- The Executioner, also known as the Man in Black, does not follow Eddie and Sue around the tower; he poses as a wax figure in the corridor next to the Torture Chamber.
- In the episode, it is bats — not rats — which stop the Executioner during the chase in the sewers.
