Pete revisit one of his childhood haunts, Braunston Marina, to meet the owner who turned around its fortunes, while Jennie discovers canal camping, an activity holiday popular with children since the 1960s. The foursome head off from Braunston taking the Oxford canal towards Banbury, discovering that the Oxford is a very different canal to those experienced earlier. Built by James Brindley to be as cheap as possible, it slowly carries them south through farmland and past sleepy villages.
