Query: "That's the sound of this planet, screaming out its rage."

"Inferno" is right up there with other well-scripted/high-action Jon Pertwee stories. In fact it's one of the best. The seven contained episodes act out rather like a thriller, and become ever so exciting as it plays out. Without giving any plot info away, the cliffhangers are fantastic (without a doubt), and are sure to make you tingle (either with fear or anticipation). "Inferno" is a must for "Doctor Who" fans and their collection.
