Pilgrimage

Eight well-known personalities, all with differing beliefs and faiths, put on backpacks and walking boots, and set out to cover the Italian section of the ancient 2,000km Via Francigena, which starts in Canterbury and finishes in Rome. They have only 15 days to tackle 1,000km, so they start their pilgrimage in the Alps, just before the Swiss-Italian border. Will this journey of a lifetime change the way they think about themselves and their beliefs?
