Michael Portillo fast tracks to the early 20th century to embark on a new series of railway journeys through Edwardian Britain. His "new" guide book, published over a hundred years ago, unlocks Britain's railways at their zenith, when some 20,000 miles of track reached into every corner of the country. Michael navigates a vibrant and optimistic Britain, at the height of its power and influence in the world, but a nation wrestling with political, social and industrial unrest at home.

His first journey follows in the footsteps of the new monarch for the new century, King Edward VII, from the grand estates of Norfolk to a bivouac on Brownsea Island. In this first episode, Michael takes a pot shot at the sport of kings at a country estate, where the king dallied with his mistress. He learns the ropes aboard an Edwardian wherry on the Norfolk Broads and joins variety performers to tap dance on Cromer Pier. In Cambridge, he investigates the student days of the young Prince of Wales and the novelist EM Forster, author of Howard's End.

Steered by his Edwardian Bradshaw's guide, Michael Portillo arrives in west Croydon, where he uncovers a once-celebrated, now forgotten, mixed-race composer with an uncannily familiar name. With the modernBritish rail network now half the size of the Edwardian one, Michael is delighted to discover a railway renaissance in Three Bridges. After inspecting a new depot and its fleet of new Class 700 trains, Michael is accorded the great honour of washing one down. Next stop Lewes, where Michael makes a beeline for Charleston, the beautiful home of the artists Vanessa Bell and Duncan Grant, where he finds every surface exquisitely decorated by the inhabitants. At Shoreham-by-Sea, Michael discovers that magnificent Edwardians in flying machines took off from the oldest licensed airport in the country. Michael takes to the skies.
