Aled Jones is in Plymouth where 400 years ago, a group of Christians embarked on an epic journey across the Atlantic that changed American history – the voyage of the Mayflower. He hears stories of the intrepid Christians who braved dangerous seas and the challenges of the New World to fulfil their calling. Aled discovers how this remarkable voyage has left its mark on political and religious life on both sides of the Atlantic. In search of the pilgrim travellers’ roots, Kate Bottley travels to Nottinghamshire to meet a living relative of William Brewster, one of the elders of the group and finds out all about his motivation. There are musical performances from Plymouth, featuring local folk musician Seth Lakeman and tenor Russell Watson, as well as congregational singing from across the UK, recorded before the current restrictions were put in place.
