Plot Synopsis

Don Wildman tears through the streets of the world's most famous cities to uncover secrets hundreds of feet beneath the pavement. Part history buff/part urban explorer, Don tells the story that visitors and residents don't get above ground.

Season 3 of CITIES OF THE UNDERWORLD premiered on Sunday, October 26, 2008 at 9pm ET/PT on History Channel. This season, he takes viewers into meandering combat tunnels, mafia escape routes, underground vaults, secret surveillance nerve centers, and forgotten underworlds that have been lost to the hands of time. Whether it's underneath London, Sicily, or Las Vegas, these are vibrant cities teeming with life, not roped off excavation sites. Join Don as he explores and investigates sites mostly unknown to all but archaeologists and locals of the land. Walk in the footsteps of history as state-of-the-art computer graphics bring to life and detail how a modern city miraculously doesn't collapse onto the past hidden safely below. The first four episodes of Season 3 feature London (Oct 26); Okinawa (Nov 2); Sicily (Nov 9); and Vegas (Nov 16).
