Cities of the Underworld - Season 3 Episode 3

The mafia instills fear around the world, but in Sicily, its presence can't be ignored. This is where the mob got its start, with the help of the underground. We'll trace the Mafia's roots back to a vigilante secret society that created an underground network where they would hold trials against corrupt city officials and execute the accused. We'll track the escape route of a most-wanted mob boss through ancient subterranean waterways, and discover a bone-crypt that holds the key to Sicily's violent past. We'll even find out how the mafia teamed up with the Allies during WWII, undermining the Axis' line of bunkers deep within the hillside and embedding themselves into Sicilian society for good.
