Plymouth to PorthcurnoIn Plymouth, Michael finds out about the Royal Navy's fighting spirit and mixes his own blend of ruin. Crossing into Cornwall, Michael learns about the last bridge to be built by one of his heroes, the engineer Isambard Kingdom Brunel. By Tre, Pol and Pen, he comes to know Cornishmen and how to prepare the perfect pasty. His journey ends in a small village which in Victorian times became a hub of global communications.
