Narrowboater Robbie Cumming begins a fresh set of adventures along the waterways of the north of England and the Midlands. He is forced to make a running repair to his narrowboat the Naughty Lass while on the Tinsley lock flight in South Yorkshire. He then cruises beneath Conisbrough's magnificent viaduct and must wait for an unusual sliding railway bridge to open on the Stainforth and Keadby Canal.
