The team reports on stories of workers from around the UK's shores. Nick Crane is in Grimsby to tell the tale of an abandoned refrigeration plant whose employees once kept Britain's biggest fishing fleet afloat, and also joins a team of drivers parking hundreds of new British cars on board a huge purpose-built transporter on the Tyne. Neil Oliver hears about the thousands of shipyard labourers on the Clyde who fought against job losses in 1971, and Tessa Dunlop is in Cumbria to reveal why the Royal Navy's guns were more accurate than anyone else's 200 years ago. Plus, comedian Ken Dodd joins poet Ian McMillan to celebrate the entertainers who worked so hard to get laughs from the holidaymakers of Blackpool in the Edwardian era.
