In the new Discovery series, Jeroen van Koningsbrugge visits the most spectacular, deserted and remote places and buildings. Together with Bob Thissen, an expert in finding and exploring abandoned structures, he discovers places where no one has set foot for years. Raw and forgotten locations, only accessible to true adventurers. They look for the stories behind these mysterious places, which sometimes reveal a shocking history. In Hungary, France, Italy and Turkey they come across hidden war bunkers, old sulfur mines, dilapidated hotels, a ghost village and, as a grisly highlight: a 17th century mass grave under a manhole cover in Genoa.
