Catacombs of Death

S1 E5: Paris, France is Europe's famous "City of Lights," but an alternate world thrives in the shadows of this capital city.

Host Eric Geller has special access to this dark underworld, where both the secrets of the living and the sins of the dead are revealed. We're peeling back the layers of time on Cities of the Underworld: Catacombs of Death.
