A Kid in King Arthur's Court

A Southern California teenager named Calvin Fuller is magically transported to 6th-century Camelot after an earthquake, where he learns he was summoned by Merlin to save the kingdom from evil Lord Belasco. Using his modern inventions, Calvin helps King Arthur retain his crown and thwart Belasco's schemes, including a romance with Princess Katey. With his time-traveling adventure coming to an end, Calvin returns to the 20th century after fulfilling his mission, leaving behind a surprising twist: he is revealed to be none other than Sarah, Arthur's daughter, who had been secretly in love with Sir Kane.
