King Boris, who hails from a European country, comes to Gotham City for a visit. Upon his arrival, there is a disturbance, which includes a clue from the Riddler. Batman and Robin investigate and get on the Riddler's trail. They are trapped by the criminal, who ties them to large wheels that will spin with ever-increasing speed until they are dead.
Did You Know?
Batman and Robin don't solve The Riddler's riddle: "What is the beginning of eternity, the end of time and space, the beginning of every end, and the end of every race?" In the following episode, it's shown on a blackboard in the Bat Cave in a list of riddles. There's a check mark next to it indicating they solved it, but they never solved it on camera nor explained its relevance. (The answer, by the way, is the letter E.) See more
The riddle itself is pretty basic. A person is a piece of wood when he's a ruler.
