Young Peter is visiting uncle in the Welsh countryside. When he finds an old knight's gauntlet, he put it on and is transported back in time to the fourteenth century. There he is the supposed son of a great Norman knight, his ancestor. He learns all about the Medieval life, and enjoys every part of his adventure (archery, hawking, jousting), even when danger arrives in the form of attack from the Welsh tribes. He helps his family lift the seige of their castle, but must finally return to his time. Will anyone believe his story? How can he convince them?
