Most of us have seen one of the countless films based on Alcatraz, from "The Birdman" to Clint Eastwood and his "Escape From Alcatraz." Over a million people every year take the ferry through the thick San Francisco fog to walk the cell blocks that housed the likes of Machine Gun Kelley and Al Capone. As usual Huell wasn't satisfied with the regular tour and went in search of the "Hidden Alcatraz". It got it's name from the Spanish word Alcatraces, or Bird Island and didn't see human inhabitants until the U.S. Military took it over in the mid 1800s. During the Civil War it was used as a prison for Southern privateers.

After the more modern prison was built in the 1930s , the old Civil War prison was covered over and virtually forgotten. Join Huell and Luis as they go under Alcatraz and discover the labyrinth of tunnels and caves that honeycomb "The Rock". There is much more to Alcatraz than meets the eye.
