Matt takes to the sea with scientists using the latest technology to get a look at Britain's Atlantis, the lost town of Dunwich, swallowed by the sea centuries ago. He later joins extreme artists who rush out to sketch the coast each time a storm tears more chunks out of it. Ellie finds out how erosion plays its part in recreating important saltmarsh habitats.

Adam Henson joins the Gloucestershire Fire Service as they train to rescue animals in emergency situations.
