Boarding a train in Budapest, Chris takes a mid-winter trip through Transylvania in search of the truth behind the story of Dracula and to find out how well the region's railway networks - which were meticulously described in Bram Stoker's 1897 classic novel - survived. Along the way he visits a place that is claimed to be the world's spookiest wood, stops off at the birthplace of the gruesome Vlad the Impaler and heads to Bucharest to look at the vast edifices of dictator Nicolae Ceausescu.
