The series that meets the vibrant community who call the UK's canal network home returns. Retired couple Debs and Mick swapped life working on the Underground for a new life cruising on their boat Rosé and Gin. As they travel through Maghull, en-route to Liverpool, they get a reminder of their time on the rails, at the Frank Hornby Heritage Centre, and they tick another Wetherspoons pub off their list. We return to Doncaster to see how newbie boaters Carrie and her mum Della, from series one, are getting on a year later; are they still afloat? And on the Grand Union Canal near Market Harborough, we meet 'bougie hippies' Adam and Lauren and their dog Shanti, as Lauren harvests a crop from their roof garden for lunch, and Adam welcomes guest Louise to the boat, who is contributing to his new book about life on the water. Meanwhile, The Canal and River Trust implement winter stoppages, so that they can see to essential maintenance and repairs on the 200-year-old network.
