In the middle of the 15th century, scribe Peter Schoeffer is dismayed to be instructed by his father to give up his beloved profession of illuminating texts in Paris. Instead he is to travel to Mainz in Germany to be apprenticed to Johann Gutenberg, an entrepreneur who has invented a new process for producing books - the printing press. Working in conditions of extreme secrecy, the men employed by Gutenberg daily face new challenges both artistic and physical as they strive to create the new books to the standard required by their master. In a time of huge turmoil in Europe and around the world, Gutenberg is relentless in pursuing his dream and wooing the powerful religious leaders whose support is critical. Peter's resistance to the project slowly dissolves as he sees that, with the guidance of a scribe such as himself, the new Bibles could be as beautiful in their way as the old.
