On the second part of the Scottish leg, Bill Oddie, Jennie Bond, Anne Diamond and Pete Waterman join the Glasgow and Edinburgh Union Canal, rising lock, stock and barge up the Falkirk wheel before heading east. Anne and Jennie encounter the ghost of William Burke - of Burke and Hare fame - as they travel through the Falkirk tunnel, which he helped build as an Irish navvy. Pete goes digging for industrial treasure at an old railway terminus and Bill gets to look down on the birds for once as the barges take to the air on the longest aqueduct in Scotland.
