Danny Trejo asks "What happens to bad guys when they die?" Many people believe Hell is a real place, so Danny's taking a journey into the afterlife to map out where the idea of Hell came from. He's exploring the darkest recesses of both the underworld and the human imagination. It's a terrifying journey through 3,000 years of ideas, each more scary than the last, taking us from ancient Greece through the birth of Christianity to medieval Europe and modern America, visiting real locations believed to be portals to Hell and using hair-raising CG to re-create ideas about the terrifying place so many people believe exists.
