Back to the Dark Ages!

Join two eleven-year-old children, living in England, on the
adventure of a lifetime who are spun back on a carousel to the
8th century AD. There they meet the Venerable Father Bede,
a famous scholar and monk, who educates them for a while in the
customs and lifestyle of the period. Then they are sent by him on
a perilous mission to take two valuable manuscripts to a king for
safekeeping before finally being spun back to our own century.
