Zak, Nick and Aaron travel to Jefferson City, MO, to investigate the infamous cellblocks and prison halls of the Missouri State Penitentiary. The prison was founded in 1836, but it wasn't long before it became known for its bloodshed and violence. Time Magazine once proclaimed it "America's bloodiest 47 acres."

Zak, Nick and Aaron answer the call to help homeowners understand the horrors that have plagued them inside their haunted, century-old, Victorian mansion. Lillian Otero and Edwin Gonzalez bought their "dream house" in 2009, but the paranormal events were so overwhelming that they eventually had to move out. The guys are determined to communicate with these relentless spirits to better understand why they keep haunting Edwin and Lillian.
