But he is not ordinary priest. Known as ‘The Pimpernel of the Vatican’, the Monsignor is the legendary organiser of the Rome Escape Line. Soon Leo is helping out with this secret network dedicated to saving the lives of escaped prisoners-of-war, partisans and Jews. But as sinister Nazi leader Kappler closes in on the network, can Leo and his sister stay out of his evil clutches?
