This time Timothy West and Prunella Scales travel from Birmingham to Braunston in Northamptonshire, for a festival of vintage canal boats. The challenging journey involves dozens of locks and a ghostly tunnel. But there's help from the family, both from actor son Sam and by Juliet, Tim's daughter from his first marriage. At Knowle Locks they meet a qualified boatman who was born on a canal boat 78 years ago. At Braunston, Tim and Pru unveil a plaque for the late Sonya Rolt, who dedicated much of her life to saving Britain's canals, and who died in 2014.
