hen Kirk and Sulu vanish into thin air from the bridge of the Enterprise, Spock sends a landing party to the planet below to locate them. What they find is an 18th century castle and a rather foppish man, Trelane, who seems to know a great deal about the Earth - even if it is the wrong time period. If truth be told, Trelane acts like a spoiled little boy and it's obvious Kirk and the others have become his playthings. They soon realize that if they are to overcome Trelane and free themselves, they must locate and destroy his power source.
