Jeroen and Bob follow the trail of the Cold War. In Hungary they explore an abandoned hotel and a bunker where time has stood still.

Jeroen and Bob explore the French Alps, where the remains of Italian forts and a hermetically sealed French bunker from WWII lie.

Jeroen and Bob travel to Sicily, Italy. They visit a ghost village that was completely destroyed by an earthquake in 1968 and they explore two old dilapidated sulfur mines. Like everywhere on this island, a link with the mafia is never far away.

Jeroen and Bob are in Turkey and explore two deserted places by the sea. They spend the night in a run-down hotel and take a boat to an island off the coast of Istanbul to visit a sanatorium where TB patients were once treated.

Jeroen and Bob travel through Northern Italy. Here they come across a castle where things that cannot stand the light of day have happened in the past. And in the city of Genoa they go under a manhole cover in a park, looking for a 17th-century mass grave.
