From beginning to end Inferno is an on-the-go thriller. The action opens with Dr Robert Langdon (Tom Hanks) in hospital with a concussion. In the midst of his confusion and weakness Langdon has visions that resemble judgment day terror, and flashbacks that seem to make no sense. It becomes apparent that he is being chased by three different lots of people because of a mysterious file in his possession. The attending doctor at the hospital, Dr Sienna Brooks (Felicity Jones), helps Langdon escape their clutches and together the two dash across Italy and then further into Europe following one clue after another. Their journey takes them to religious shrines that date back to the infamous Middle Ages and the time of the Black Plague. A modern-day maniac, Bertrand Zobrist (Ben Foster), is linked to the file Langdon decodes, and it becomes apparent that Zobrist wants to unleash spores of that deadly ancient plague into the water system. By doing this he will wipe out half the Earth’s human beings, thus sorting out the problem of overpopulation and evil. Langdon and Brooks have limited time to find the virus and stop the attack.
